That does make sense.  But let me try one last time, before doing
that.  (I should have sat down and thought this through carefully
before sending the first version --- sorry.)

Though the first two iterations of the patch were pretty ugly, the
third was just 's/vi/"$editor"/g' after setting editor and bailing out
if it does not consist of lowercase letters.  As you mentioned, it
makes more sense to skip only the "vi" part of the test.

Tested with DEFAULT_EDITOR=vi, vim, /usr/bin/nonexistent.
