The existing format for commit logs will remain the default, but
this change allows customization of the `--date=format:` and
`--pretty=format:` arguments passed to `git log`. For example, I
prefer having the time of day a commit was made, and having the
time in front, which can now be done with these options:
```
git:
dateFormat: "%H:%M %d %b %y"
commitFormat: "[forestgreen]%h [grey]%cd [white]%s [grey]%an[white]"
```
(sorry, this doesn't update documentation - if you let me know
what files to edit for those and how to "build" the docs to update
them, I can try to do that better in future changes)
After setting up the git module with multiple repos and switching
between them, I observed some graphical wonkiness in the display:

After adding some log statements, I tracked it down to the
`GitRepo.Repository` field having a newline in it after it's set
from a command execution's stdout. This change strips the
repository path of spaces when assigning to the `Repository` field,
which fixes the display issues.
