That would be better, since the binary may be running on a system

I think we already do something like this:
devzero:260> EDITOR=foobar octave-bug
/usr/bin/octave-bug: line 226: foobar: command not found
problems with edit -- no bug report submitted
saving message in /home/jwe/dead-octave-bug-1
OK, I just checked the bashbug script (which I used as the starting
point for octave-bug way back when) and it now uses
if [ -z "$DEFEDITOR" ] && [ -z "$EDITOR" ]; then
if [ -x /usr/bin/editor ]; then
DEFEDITOR=editor
elif [ -x /usr/local/bin/ce ]; then
DEFEDITOR=ce
elif [ -x /usr/local/bin/emacs ]; then
DEFEDITOR=emacs
elif [ -x /usr/contrib/bin/emacs ]; then
DEFEDITOR=emacs
elif [ -x /usr/bin/emacs ]; then
DEFEDITOR=emacs
elif [ -x /usr/bin/xemacs ]; then
DEFEDITOR=xemacs
elif [ -x /usr/contrib/bin/jove ]; then
DEFEDITOR=jove
elif [ -x /usr/local/bin/jove ]; then
DEFEDITOR=jove
elif [ -x /usr/bin/vi ]; then
DEFEDITOR=vi
else
echo "$0: No default editor found: attempting to use vi" >&2
DEFEDITOR=vi
fi
fi
: ${EDITOR=$DEFEDITOR}
so I'll copy this method.
