Simplify-fuzzy gets stuck in (seemingly) endless loop

Simplify-fuzzy gets stuck in (seemingly) endless loop

[Niklas Morberg]

When trying to enter a group it takes forever. To find out
what's happening, I toggled debug on quit and took a look.
This is the backtrace:

* re-search-forward("^[ 	]*\\([Rr][Ee]\\(\\[[0-9]*\\]\\)*:[ 	]*\\)*[ 	]*" nil t)
  gnus-simplify-subject-fuzzy("RE: Mjukvarulicenser")
  gnus-map-function((gnus-simplify-subject-fuzzy gnus-simplify-all-whitespace) "RE: Mjukvarulicenser")

When i hit `d' four times in a row this happens for each step:

Debugger entered--entering a function:
* re-search-forward("^[ 	]*\\([Rr][Ee]\\(\\[[0-9]*\\]\\)*:[ 	]*\\)*[ 	]*" nil t)
  gnus-simplify-subject-fuzzy("RE: Mjukvarulicenser")

Debugger entered--returning value: 1
  re-search-forward("^[ 	]*\\([Rr][Ee]\\(\\[[0-9]*\\]\\)*:[ 	]*\\)*[ 	]*" nil t)

Debugger entered--entering a function:
* replace-match("")

Debugger entered--returning value: nil
  replace-match("")

The fifth time I hit `d', I go back to the re-search-forward
and and the cycle repeats itself. It never stops.

Fresh CVS from just now, but I have seen this before. The way
I "solved" it then was to turn off all fuzzy matching. After
a while when things seemed normal, I turned the fuzziness
back on and things were fine. The problems reappeared after a
restart of emacs.

Odd.

If you eval the following, what happens?

(gnus-map-function
 '(gnus-simplify-subject-fuzzy gnus-simplify-all-whitespace)
 "RE: Mjukvarulicenser")

It returns "Mjukvarulicenser". But I haven't seen this
problem in a while and can not reproduce it. I'll shout if
it pops up again...
