From: David Aguilar Date: Thu, 26 May 2011 03:37:12 +0000 (-0700) Subject: setup: Provide GIT_PREFIX to built-ins X-Git-Tag: v1.7.7-rc0~114^2~3 X-Git-Url: https://git.tokkee.org/?a=commitdiff_plain;h=1f5d271f5e8f7b1e2a5b296ff43ca4087eb08244;p=git.git setup: Provide GIT_PREFIX to built-ins GIT_PREFIX was added in 7cf16a14f5c070f7b14cf28023769450133172ae so that aliases can know the directory from which a !alias was called. Knowing the prefix relative to the root is helpful in other programs so export it to built-ins as well.
