[ disclaimer: I've not looked at the proposed patch yet ]
It seems like this ought to be fairly easily surmountable as long as
the patch is designed for failure. The fallback position is just that
the line number does nothing, ie \ef foo just opens the editor and
doesn't try to position the cursor anywhere special; nobody can complain
about that because it's no worse than before. What we need is to not
try to force positioning if we don't recognize the editor. I'm tempted
to suggest forgetting about any user-configurable parameter and just
provide code that strcmp's the $EDITOR value to see if it recognizes the
editor name, otherwise do nothing.
