git_path from config.yml not used

[mblythe86]

I'm attempting to run gitlist on an ancient system where /usr/bin/git is version 1.7.1.

As a result, I'm getting an error unknown option 'short' when the code tries to call git symbolic-ref --short HEAD.

Since git_path is provided in the example config.yml, I assumed setting that would fix my issue, however, when I set it to the path of a more recent version of git, the error persists.

As far as I can tell, the git_path attribute in config.yml is unused. I'd expect src/SCM/System/Git/CommandLine.php to have some code to get the value from the config, but it doesn't. I also don't find anything in the ExecutableFinder class. I do see another reference to git_path in config/services.yml that seems to suggest that it is used to set $path, but it's not clear to me how this is supposed to work.

As a workaround, I manually set $path in the __construct function, and my errors have stopped.
