[PATCH] Show modified files in git-ls-files

[Brian Gerst <bgerst@didntduck.org>]

[-- Attachment #1: Type: text/plain, Size: 425 bytes --]

Add -m/--modified to show files that have been modified wrt. the index.

M was already taken so the tag for modifified files is C (changed).

$ git-ls-files -m -t
C Documentation/git-ls-files.txt
C ls-files.c
