[PATCH] Set GIT_PATHNAME_PREFIX with aliases.

From: Jared Hance <jaredhance@gmail.com>
Date: May 5, 2010, 00:25 UTC
Message-ID: <1273019122.16093.6.camel@ubuntu.ubuntu-domain>

The environment variable GIT_PATHNAME_PREFIX passes on the current working directory (where the git command was called from) to shell aliases (aliases that begin with "!"). This allows these shell aliases to know the directory that the git command was called from.
