RE too deep

[Loren Schall]

Hi,

Sporadically over the last several versions I've been getting an error
about regular-expression recursion too deep when I try to enter certain
large binary groups I'd rather not name.  Sorry, I didn't note the exact
error message.

The following patch seems to alleviate the problem.  I suspect that the
`[^()]' part of the annotated regular expression in
gnus-simplify-buffer-fuzzy is/was trying to match across lines (which
is what emacs does, contrary to the usual unix interpretation).
