OK. Attached find my latest version of whitespace.el. Please try it
for all five sorts of whitespace bemoaned by that program and whether
the cleanup routines fix it in the expected manner.
Interesting things again! I tried this latest whitespace.el and found
1. whitespace-buffer on slowtst.el takes ~9 seconds (=the same result
what I got with your previous fix) IF point is at the beginning of the
buffer. If point is somewhere down (e.g. at (point-max))
whitespace-buffer finishes in ~2 seconds!?
2. newest whitespace-buffer on my "original most problematic" file
needs ~ 55 seconds (before fix this was ~3(?) minutes and unexpected
delay occured also at file opening and at file closing
"automatically"; now file opening and closing is normal fast
(=immediate)) IF point is at top of the buffer. If point is at about
the middle, whitespace-buffer needs ~25 seconds to finish. If point is
at (point-max), whitespace-buffer finishes in 3 seconds!
So if you could find the reason of this strange difference related to
(point), then there would be no performace problem with whitespace.
