If you're in for a bit of coding stunts :-) I guess we could have one
last try, using your name, Barry's macro and shorter variable names:
(defmacro dcbl-set-bounds (start end)
`(progn
(if (equal ,start ,end)
(setq ,start (point-min)
,end (point-max))
(setq ,start (or ,start (point-min))
,end (or ,end (point-max))))
(setq ,start (list ,start ,end)
,start (sort ,start '<)
,end (second ,start)
,start (first ,start))))
it should be OK to use one of the variables being changed as the temp
var, shouldn't it?
Cheers,
