23.0.60; Womang hangs on some links |

Hello,
Starting with a fresh checkout of the emacs source tree, Woman hangs
when following some links to non-existent man pages. It happenned when
I was looking at the procmailrc(5) page, and wanted to follow the
regexp(5) link. At that moment, emacs stopped responding. The
regexp(5) page doesn't exist on my system.
However, when trying to come up with a minimal example, I saw that it
doesn't happen with all broken links. Here are the steps to reproduce :
1. Save the following snippet to a file, say hangs.1 :
---------------- 8< ----------------
.TH "hang" 1
.SH NAME
hang \- small man page that hangs Emacs
.SH DESCRIPTION
If you follow this link :
.BR regexp (5)
, Emacs will hang.
However, if you follow this one :
.BR nonexistent (5)
, Emacs won't hang.
---------------- 8< ---------------
2. Start emacs with emacs -Q, and visit hangs.1 with M-x
woman-find-file.
3. Put point on nonexistent(5) and press RET : as expected, Woman says
that the page cannot by found.
4. Put point on regexp(5), and press RET : emacs with stop responding,
consuming 100% of the CPU.
A side question : given the recent discussions about the state of the
toolchain used, I did 'rm -fr emacs ; cvs -d... co emacs ; cd emacs ;
./configure ; make bootstrap'. Is there a method less network and
CPU-hungry ?
