[PATCH] add status.relativePaths config variable

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



The output of git-status was recently changed to output
relative paths. Setting this variable to false restores the
old behavior for any old-timers that prefer it.

So here is a config option to turn it off; I don't think there should be
any consistency problems, since git-status output is meant to be
human-readable (and after all, we just changed it :) ).

This patch also contains a small buglet fix in the neighboring code
where we didn't stop trying to match "color.status.*" even after we used
it to set the status color.
