Subject: [PATCH] Fix _forgit_diff on macOS (#375)

In bash 3.2 uninitialized arrays contain one entry: an empty string,
whereas in modern versions of bash they do not contain any entry. Make
sure the $commits and $files arrays are explicitly initialized as empty
arrays to allow git to fall back to diffing local changes instead of
trying to diff against a revision with a name of an empty string.
