Ah. Well, it looks like all but git-merge-resolve.sh run `.
git-sh-setup`, so we know that GIT_EXEC_PATH must in their PATH (and
at the front unless the script was invoked directly).
git-merge-resolve.sh does not do this, so I suppose if the user ran
$GIT_EXEC_PATH/git-merge-resolve directly, and also had a custom
git-merge-index executable in their PATH, that would switch to running
the git merge-index built-in instead.
