Fixed trailing empty docs

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.

-yq is a lightweight and portable command-line YAML processor. It aims to be the jq or sed of yaml files.
-
 Usage:
   yq [flags]
   yq [command]
 
 Available Commands:
-  delete      yq d [--inplace/-i] [--doc/-d index] sample.yaml a.b.c
+  compare     yq x [--prettyPrint/-P] dataA.yaml dataB.yaml 'b.e(name==fr*).value'
+  delete      yq d [--inplace/-i] [--doc/-d index] sample.yaml 'b.e(name==fred)'
   help        Help about any command
   merge       yq m [--inplace/-i] [--doc/-d index] [--overwrite/-x] [--append/-a] sample.yaml sample2.yaml
   new         yq n [--script/-s script_file] a.b.c newValue
   prefix      yq p [--inplace/-i] [--doc/-d index] sample.yaml a.b.c
-  read        yq r [--doc/-d index] sample.yaml a.b.c
-  write       yq w [--inplace/-i] [--script/-s script_file] [--doc/-d index] sample.yaml a.b.c newValue
+  read        yq r [--printMode/-p pv] sample.yaml 'b.e(name==fr*).value'
+  validate    yq v sample.yaml
+  write       yq w [--inplace/-i] [--script/-s script_file] [--doc/-d index] sample.yaml 'b.e(name==fr*).value' newValue
 
 Flags:
-  -h, --help      help for yq
-  -t, --trim      trim yaml output (default true)
-  -v, --verbose   verbose mode
-  -V, --version   Print version information and quit
+  -h, --help          help for yq
+  -I, --indent int    sets indent level for output (default 2)
+  -P, --prettyPrint   pretty print
+  -j, --tojson        output as json. By default it prints a json document in one line, use the prettyPrint flag to print a formatted doc.
+  -v, --verbose       verbose mode
+  -V, --version       Print version information and quit
 
 Use "yq [command] --help" for more information about a command.

-<p>To convert output to json, use the --tojson (or -j) flag. This is supported by all commands.</p>
-<p>Each matching yaml node will be converted to json and printed out on a separate line.</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
-</code></pre>
-
-<p>will output</p>
-<pre><code class="json">{&quot;b&quot;:{&quot;c&quot;:2}}
-</code></pre>
-
-<p>Given a sample.yaml file of:</p>
-<pre><code class="yaml">bob:
-  c: 2
-bab:
-  c: 5
-</code></pre>
-
-<p>then</p>
-<pre><code class="bash">yq r -j sample.yaml b*
-</code></pre>
-
-<p>will output</p>
-<pre><code class="json">{&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

-
-<p>will output</p>

-Yaml files can be merged using the 'merge' command. Each additional file merged with the first file will
-set values for any key not existing already or where the key has no value.
-
-```
-yq m <yaml_file> <path>...
-```
-
-
-## Merge example
-Given a data1.yaml file of:
-```yaml
-a: simple
-b: [1, 2]
-```
-and data2.yaml file of:
-```yaml
-a: other
-c:

-```
-will output:
-```yaml
-a: simple
-b: [1, 2]
-c:
-  test: 1
-```
-
-## Updating files in-place
-```bash
-yq m -i data1.yaml data2.yaml
-```
-will update the data1.yaml file with the merged result.
-
-## Overwrite values
-Given a data1.yaml file of:
-```yaml
-a: simple
-b: [1, 2]
-```
-and data2.yaml file of:
-```yaml
-a: other

-```
-will output:

-
-### Overwrite values with arrays
-Given a data1.yaml file of:
-```yaml
-a: simple
-b: [1, 2]
-```
-and data3.yaml file of:
-```yaml
-b: [3, 4]
-c:
-  test: 2
-  other: true
-d: false
-```
-then
-```bash
-yq m -x data1.yaml data3.yaml
-```
-will output:
-```yaml
-a: simple
-b: [3, 4]
-c:
-  test: 2
-  other: true
-d: false
-```
-
-Notice that 'b' does not result in the merging of the values within an array. 
-
-## Append values with arrays
-Given a data1.yaml file of:
-```yaml
-a: simple
-b: [1, 2]
-d: hi
-```
-and data3.yaml file of:
-```yaml
-a: something
-b: [3, 4]
-c:

-
-Note that the 'b' array has concatenated the values from the second data file. Also note that other map keys are not overridden (field a).
-
-## Multiple Documents
-### Merge into single document

-Path expressions are used to deeply navigate and match particular yaml nodes.
-
-_As a general rule, you should wrap paths in quotes to prevent your CLI from processing '*, []' and other special characters._
-
-## Simple expressions
-
-### Maps
-
-a.b.c
-
-```yaml
-a:
-  b:
-    c: thing # MATCHES
-```
-
-### Arrays
-
-a.b[1].c
-
-```yaml
-a:
-  b:
-  - c: thing0 
-  - c: thing1 # MATCHES
-  - c: thing2
-```
-
-#### Appending to arrays
-(e.g. when using the write command)
-
-a.b[+].c
-
-
-```yaml
-a:
-  b:
-  - c: thing0 
-```
-
-Will add a new entry:
-
-```yaml
-a:
-  b:
-  - c: thing0 
-  - c: thing1 # NEW entry from [+] on B array.
-```
-
-
-## Splat
-
-### Maps
-a.*.c
-
-```yaml
-a:
-  b1:
-    c: thing # MATCHES
-    d: whatever
-  b2:
-    c: thing # MATCHES
-    f: something irrelevant
-```
-
-#### Prefix splat
-
-bob.item*.cats
-
-```yaml
-bob:
-  item:
-    cats: bananas # MATCHES
-  something:
-    cats: lemons
-  itemThing:
-    cats: more bananas # MATCHES
-  item2:
-    cats: apples # MATCHES
-  thing:
-    cats: oranges
-```
-
-### Arrays

-    d: what..ever
-  - c: thing1 # MATCHES
-    d: blarh
-  - c: thing2 # MATCHES
-    f: thingamabob
-```
-
-## Deep Splat
-
-'**' will match arbitrary nodes for both maps and arrays:
-
-a.**.c
-
-```yaml
-a:
-  b1:
-    c: thing1 # MATCHES
-    d: cat cat
-  b2:
-    c: thing2 # MATCHES
-    d: dog dog

-          c: thing4 # MATCHES
-          d: boop
-    - d: mooo
-```
-
-
-## Search by children nodes
-
-a.(b.d==cat).b.c
-

-  - b:

-      d: cat
-    ba: also meowy
-```
-
-
-## Special Characters
-
-
-### Keys with dots
-When specifying a key that has a dot use key lookup indicator.
-
-```yaml
-b:
-  foo.bar: 7
-```
-
-```bash
-yaml r sample.yaml 'b[foo.bar]'
-```
-
-```bash
-yaml w sample.yaml 'b[foo.bar]' 9
-```
-
-Any valid yaml key can be specified as part of a key lookup.
-
-Note that the path is in quotes to avoid the square brackets being interpreted by your shell.
-
-### Keys (and values) with leading dashes
-The flag terminator needs to be used to stop the app from attempting to parse the subsequent arguments as flags, if they start if a dash.
-
-```bash
-yq n -j -- --key --value
-```
-
-Will result in
-
-```
---key: --value
