ability to use Cygwin's git instead of msysGit

msysGit doesn't work too well for me; for some reason it can't set
executable bits. This causes all files that are committed as 755 to appear
always-modified unless you set the repo to ignore perms.

Cygwin's git works perfectly for me, on the other hand.
