Fixed explode for aliases to scalars

The program generates a path for every leaf node in the
file-to-be-merged. It does not escape them if they contain a dot, as
the path-expressions document mentions is necessary.

Add in a test for this condition. Verified it fails without the fix.

+Major release! Upgraded underlying yaml parser, re-written majority of yq. This has brought on a number of features that have been in demand for a while (see below).
+
+This is in beta and needs some community feedback and testing :)

 # New Features
-  - Keeps yaml comments and formatting (string blocks are saved, number formatting is preserved, so it won't drop off trailing 0s for values like 0.10, which is important when that's a version entry )
-  
-  - Handles anchors! (doc link)
-  - Can specify yaml tags (e.g. !!int), quoting values no longer sufficient, need to specify the tag value instead.
-  - Can print out matching paths and values when splatting (doc link)

-<p>To convert output to json, use the --tojson (or -j) flag. This can only be used with the read command.</p>
-<p>Given a sample.yaml file of:</p>
-<pre><code class="yaml">b:
-  c: 2
-</code></pre>
-
-<p>then</p>
-<pre><code class="bash">yq r -j sample.yaml b.c
-</code></pre>
-
-<p>will output</p>
-<pre><code class="json">{&quot;b&quot;:{&quot;c&quot;:2}}
-</code></pre>
-
-<h3 id="json-to-yaml">Json to Yaml<a class="headerlink" href="#json-to-yaml" title="Permanent link">&para;</a></h3>
-<p>To read in json, just pass in a json file instead of yaml, it will just work :)</p>
-<p>e.g given a json file</p>
-<pre><code class="json">{&quot;a&quot;:&quot;Easy! as one two three&quot;,&quot;b&quot;:{&quot;c&quot;:2,&quot;d&quot;:[3,4]}}
-</code></pre>
-
-<p>then</p>
-<pre><code class="bash">yq r sample.json
-</code></pre>
-
-<p>will output</p>
-<pre><code class="yaml">a: Easy! as one two three
-b:
-  c: 2
-  d:

-                
-                <p>Yaml files can be created using the 'new' command. This works in the same way as the write command, but you don't pass in an existing Yaml file. Currently this does not support creating multiple documents in a single yaml file.</p>
-<pre><code>yq n &lt;path&gt; &lt;new value&gt;
-</code></pre>
-
-<h3 id="creating-a-simple-yaml-file">Creating a simple yaml file<a class="headerlink" href="#creating-a-simple-yaml-file" title="Permanent link">&para;</a></h3>
-<pre><code class="bash">yq n b.c cat
-</code></pre>
-
-<p>will output:</p>
-<pre><code class="yaml">b:
-  c: cat
-</code></pre>
-
-<h3 id="creating-using-a-create-script">Creating using a create script<a class="headerlink" href="#creating-using-a-create-script" title="Permanent link">&para;</a></h3>
-<p>Create scripts follow the same format as the update scripts.</p>
-<p>Given a script create_instructions.yaml of:</p>
-<pre><code class="yaml">b.c: 3
-b.e[+].name: Howdy Partner
-</code></pre>
-
-<p>then</p>
-<pre><code class="bash">yq n -s create_instructions.yaml
-</code></pre>
-
-<p>will output:</p>
-<pre><code class="yaml">b:
-  c: 3
-  e:
-    - name: Howdy Partner
-</code></pre>
-
-<p>You can also pipe the instructions in:</p>
-<pre><code class="bash">cat create_instructions.yaml | yq n -s -
-</code></pre>
-
-<h3 id="keys-with-dots">Keys with dots<a class="headerlink" href="#keys-with-dots" title="Permanent link">&para;</a></h3>
-<p>When specifying a key that has a dot use key lookup indicator.</p>
-<pre><code class="yaml">b:
-  foo.bar: 7
-</code></pre>
-
-<pre><code class="bash">yaml r sample.yaml 'b[foo.bar]'
-</code></pre>
-
-<pre><code class="bash">yaml w sample.yaml 'b[foo.bar]' 9
-</code></pre>
-
-<p>Any valid yaml key can be specified as part of a key lookup.</p>
-<p>Note that the path is in quotes to avoid the square brackets being interpreted by your shell.</p>
-<h3 id="keys-and-values-with-leading-dashes">Keys (and values) with leading dashes<a class="headerlink" href="#keys-and-values-with-leading-dashes" title="Permanent link">&para;</a></h3>
-<p>If a key or value has leading dashes, yq won't know that you are passing a value as opposed to a flag (and you will get a 'bad flag syntax' error).</p>
-<p>To fix that, you will need to tell it to stop processing flags by adding '--' after the last flag like so:</p>
-<pre><code class="bash">yq n -t -- --key --value
-</code></pre>
-
-<p>Will result in</p>
-<p><code>`
---key: --value</code></p>

-<h3 id="arrays">Arrays<a class="headerlink" href="#arrays" title="Permanent link">&para;</a></h3>
-<p>You can give an index to access a specific element:

-  e:
-    - name: fred
-      value: 3
-    - name: sam

-
-<p>then</p>
-<pre><code>yq r sample.yaml 'b.e[1].name'
-</code></pre>
-
-<p>will output 'sam'</p>
-<p>Note that the path is in quotes to avoid the square brackets being interpreted by your shell.</p>
-<h3 id="array-splat">Array Splat<a class="headerlink" href="#array-splat" title="Permanent link">&para;</a></h3>
-<p>e.g.: given a sample file of</p>
-<pre><code class="yaml">b:
-  e:
-    - name: fred
-      value: 3
-    - name: sam
-      value: 4
-</code></pre>
-
-<p>then</p>
-<pre><code>yq r sample.yaml 'b.e[*].name'
-</code></pre>
-
-<p>will output:</p>
-<pre><code>- fred
-- sam
-</code></pre>
-
-<p>Note that the path is in quotes to avoid the square brackets being interpreted by your shell.</p>
-<h3 id="keys-with-dots">Keys with dots<a class="headerlink" href="#keys-with-dots" title="Permanent link">&para;</a></h3>
-<p>When specifying a key that has a dot use key lookup indicator.</p>
-<pre><code class="yaml">b:
-  foo.bar: 7
-</code></pre>
-
-<pre><code class="bash">yaml r sample.yaml 'b[foo.bar]'
-</code></pre>
-
-<pre><code class="bash">yaml w sample.yaml 'b[foo.bar]' 9
-</code></pre>
-
-<p>Any valid yaml key can be specified as part of a key lookup.</p>
-<p>Note that the path is in quotes to avoid the square brackets being interpreted by your shell.</p>
-<h3 id="keys-and-values-with-leading-dashes">Keys (and values) with leading dashes<a class="headerlink" href="#keys-and-values-with-leading-dashes" title="Permanent link">&para;</a></h3>
-<p>If a key or value has leading dashes, yq won't know that you are passing a value as opposed to a flag (and you will get a 'bad flag syntax' error).</p>
-<p>To fix that, you will need to tell it to stop processing flags by adding '--' after the last flag like so:</p>
-<pre><code class="bash">yq n -t -- --key --value
-</code></pre>
-
-<p>Will result in</p>
-<p><code>`
---key: --value</code></p>

-                <h3 id="keys-with-dots">Keys with dots<a class="headerlink" href="#keys-with-dots" title="Permanent link">&para;</a></h3>
-<p>When specifying a key that has a dot use key lookup indicator.</p>
-<pre><code class="yaml">b:
-  foo.bar: 7
-</code></pre>
-
-<pre><code class="bash">yaml r sample.yaml 'b[foo.bar]'
-</code></pre>
-
-<pre><code class="bash">yaml w sample.yaml 'b[foo.bar]' 9
-</code></pre>
-
-<p>Any valid yaml key can be specified as part of a key lookup.</p>
-<p>Note that the path is in quotes to avoid the square brackets being interpreted by your shell.</p>
-<h3 id="keys-and-values-with-leading-dashes">Keys (and values) with leading dashes<a class="headerlink" href="#keys-and-values-with-leading-dashes" title="Permanent link">&para;</a></h3>
-<p>If a key or value has leading dashes, yq won't know that you are passing a value as opposed to a flag (and you will get a 'bad flag syntax' error).</p>
-<p>To fix that, you will need to tell it to stop processing flags by adding '--' after the last flag like so:</p>
-<pre><code class="bash">yq n -t -- --key --value
-</code></pre>
-
-<p>Will result in</p>
-<pre><code>--key: --value
-</code></pre>

-Note that the path is in quotes to avoid the square brackets being interpreted by your shell.
-
-### Keys (and values) with leading dashes
-If a key or value has leading dashes, yq won't know that you are passing a value as opposed to a flag (and you will get a 'bad flag syntax' error).
-
-To fix that, you will need to tell it to stop processing flags by adding '--' after the last flag like so:
-
-
-```bash
-yq n -t -- --key --value
-```
-
-Will result in
-
-```
---key: --value
