[PATCH 1/1] t0001: fix on case-insensitive filesystems

[Johannes Schindelin via GitGitGadget]

From: Johannes Schindelin <johannes.schinde...@gmx.de>

On a case-insensitive filesystem, such as HFS+ or NTFS, it is possible
that the idea Bash has of the current directory differs in case from
what Git thinks it is. That's totally okay, though, and we should not
expect otherwise.

Reported by Jameson Miller.
