From 7cf16a14f5c070f7b14cf28023769450133172ae Mon Sep 17 00:00:00 2001 From: Michael J Gruber Date: Wed, 27 Apr 2011 10:36:27 +0200 Subject: [PATCH] handle_alias: provide GIT_PREFIX to !alias Provide an environment variable GIT_PREFIX which contains the subdirectory from which a !alias was called (i.e. 'git rev-parse --show-prefix') since these cd to the to level directory before they are executed.
