Subject: 24.0.50; woman leaves \& in man page header
Date: Thu, 13 Jan 2011 21:01:42 -0800

I typed

M-x w o m a n <return> g i t - r e m o t e <return>

and saw the man page for the "git-remote" command.

At the top of that page, I saw

        GIT-REMOTE(1) -- 10/30/2010 -- Git 1\&.7\&.3\&.2 -- Git Manual

The \& in the third section are bogus; "M-x man git-remote" correctly
omits them.

I've checked in what I think is a correct fix into the trunk.

(I'm hardly an expert in this part of the code, so it's better not to
put it in the branch in case it turns out to be a wrong fix.)

You jinxed it. ;)
It seems to cause problems. man.1 (attached) renders worse in the
current trunk than in Emacs 23.3. The woman-log buffer has many entries
that do not appear in 23.3:

**  Escape ignored: \- -> -
    [many times]
**  Escape ignored: \f -> f
    [many times]
**  ..  request ignored!
    [several times]
**  Numeric/register argument error: w'man 'u

An example of a section that renders worse is

   The following conventions apply  to the SYNOPSIS section and
   can be used as a guide in other sections.

   fBbold textfR <at> T{
   type exactly as shown.
   T}

In 23.3, "bold text" is correctly rendered in bold.

Also the spaces are missing between "man" and the arguments in the
following section:
   
   EXAMPLES
   
       man ls
           Display the manual page for the item (program) ls.

[man.1.gz (application/octet-stream, attachment)]

My version of Groff (1.19) also emits quite a bit of diagnostics for
that man page.

So does Groff (invoked by my clone of `man'):

tbl 1.21 has no problem with that.

I'm sure it doesn't.  I was just saying that bitrot is not limited to
woman.el.

OK, I checked in a fix.
