From 1f5d271f5e8f7b1e2a5b296ff43ca4087eb08244 Mon Sep 17 00:00:00 2001 From: David Aguilar Date: Wed, 25 May 2011 20:37:12 -0700 Subject: 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.
