If you call "git xyz", but git-xyz is a script, you will exec the git 
wrapper first, which will then exec git-xyz.  That is an unnecessary exec.

Since the places you touched are already in a git script (i.e. it was 
already called with PATH extended to git's libexec/ directory, if there is 
one), we can avoid that extra exec.

The git-<command> syntax _is_ phased out, but in several steps.  Let's not 
do the third step before the first, otherwise we'll trip.
