PATCH: manpage reference transforms

[Clint Adams <schizo@xxxxxxxxxx>]

This monster makes the manpages refer to each other properly,
except for "zsh", which I didn't replace for obvious reasons.
The slashes should probably be changed to commas for
consistency's sake.

AFAICT the only two major things not yet being transformed
are the references to zsh.1 in the manpages, and the Texinfo
description.
