Subject: doc: manpage: remove maximum title length

DocBook Stylesheets limit the size of the manpage titles for some
reason.

Even some of the longest git commands have no trouble fitting in 80
character terminals, so it's not clear why we would want to limit titles
to 20 characters, especially when modern terminals are much bigger.

For example:

  --- a/git-credential-cache--daemon.1
  +++ b/git-credential-cache--daemon.1

Moreover, asciidoctor manpage backend doesn't limit the title length, so
we probably want to do the same for docbook backends for consistency.
