As mentioned in this answer, since Git 1.8.2 you can use core.commentchar
config value to change commit message comments to something else than the default #
(hashmark or hashsign).
That is a life-saver e.g. if your commit message policy wants you to start commit message with ticket number:
#123 Fixed array indices
Sad part is that this breaks Vim syntax highlighting.
How can you bring the beauty back?
