* The previous commands were Lower CamelCase style and had no equivalent
short options. If you wanted to see the branch tree via non-interactive
mode, you always needed to supply "branchTree" as the passing argument to
the git-quick-stats script.
This commit changes the argument style to be more akin to the POSIX and GNU
styles of arguments commonly seen in many other applications. As of this
commit, there is no compatibility with legacy commands, so those who have
been using the old commands will unfortunately need to get familiar with the
new ones. All documentation and tests have been updated accordingly to
reflect the new changes.
* The main interactive loop contained a non-variable constant that was only
getting parsed correctly due to legacy fallback behavior. This commit fixes
the main loop and cleans up the formatting a little bit.
* Added -r to more areas where read reads in a variable to help prevent
it from mangling backslashes.
* Changed everything to use bash's built-in [[ notation and did some minor
formatting changes to reduce the LOC.
* Removed some unnecessary echo statements and did some other minor cleanup.
