Re: [PATCH] t3502: Disambiguate between file and rev by adding --

Brian Gernhardt, Sun, Nov 04, 2007 16:31:26 +0100:

This test failed because git-diff didn't know if it was asking for the
file "a" or the branch "a".  Adding "--" at the end of the ambiguous
commands allows the test to finish properly.

To be precise: this is ambiguous only on case-challenged filesystems
