reproducible problem with perl.ssh version 2.11

[Poyner, Brandon]

I tried contacting the last maintainer of perl.ssh (Denis Girou) with
this problem but didn't hear back.  

It takes about 22.5 hours of CPU time on a 2.2Ghz Pentium4 for perl.ssh
to process the following regular expression:
 
s/[^\w\.\s\|\,\'\<\>\?\;\:address@hidden&\*\(\)\/\?\{\}q]
//g;

I'm fairly sure the problem is in perl.ssh, as I've made minor changes
to perl.ssh and the time to process drops to under 1 second.  Also
selecting another style sheet is equally as fast.

I filed a bug report with RedHat, who seemed to agree there was a
problem but didn't know the appropriate fix:
https://bugzilla.redhat.com/show_bug.cgi?id=252183

OS: RedHat Enterprise Linux 4
a2ps version:  a2ps-4.13b
perl.ssh version:  2.11
