Subject: git: Automatically create non-existing repositories.
X-Git-Url: https://git.stderr.nl/gitweb?p=matthijs%2Fservers%2Fdrsnuggles.git;a=commitdiff_plain;h=35359cf1b51f5d677b6351d7529f1f4986c0f7b8

git: Automatically create non-existing repositories.

This extends the git-prepend-base script to automatically create a bare
git repository when it does not exist yet. This also makes the option
handling slightly more robust, to prevent the script from messing with
arguments that aren't git repository paths at all.
