RE: save-excursion not working - despite NO-ERROR in search-forward-rege

Gnuist,

I think the problem is your use of (end-of-buffer) which is a function of 
motion, not location. It's *info* documentation also has this note: `*Warning:* 
Don't use this function in Lisp programs!'.

Try using (point-max) instead.

I hope this helps.

,Doug
