From 47d65924a69576bd9f3254f7055de6b37a359596 Mon Sep 17 00:00:00 2001 From: David Aguilar Date: Sat, 11 Apr 2009 20:41:56 -0700 Subject: mergetool--lib: simplify API usage by removing more global variables The mergetool--lib scriplet was tricky to use because it relied upon the existance of several global shell variables. This removes more global variables so that things are simpler for callers. A side effect is that some variables are recomputed each time run_merge_tool() is called, but the overhead for recomputing them is justified by the simpler implementation.
