Subject: Teach "git diff" to handle filenames starting with '-'
X-Git-Tag: v0.99.9~92
X-Git-Url: https://git.tokkee.org/?a=commitdiff_plain;h=ea51d416c02bb26e9d7600f87b27deb42752e6b5;p=git.git

Teach "git diff" to handle filenames starting with '-'

It adds "--" to the git-diff.sh scripts, to keep any filenames that start
with a "-" from being confused with an option.

But in order to do that, it needs to teach git-diff-files to honor "--".
