rst2man does a poor job of creating man pages that can be read on Solaris.
Some of the changes in this patch make the Solaris *roff tools do the right
thing:

  - Getting rid of the rst2man header before the SYNOPSIS

  - Changing "\(aq" to "'", and making sure that single quotes don't start
    a line (at least in a couple of places where it's not safe)

  - Changing ".ft C" and ".ft P" to simply ".ft"

  - Removing "\%" and "\:"

Groff also seems to have as much trouble with the .INDENT/.UNINDENT macros
as Solaris *roff, de-indenting paragraphs that shouldn't be, so we use
.RS/.RE instead.  It's not as fancy, but seems to do the job.

Applying this patch has no effect in the normal userland build (it can't
run automatically until docutils is delivered), but it enables a "gmake
patches/manpage.patch" to regenerate the manpages with the updated text
(found in rst.patch) with the patched hgmanpage.py, and updates the
manpage.patch file.
