[wwwdocs] Simplify cvs.html

[Gerald Pfeifer <gerald at pfeifer dot com>]

Based on some troubles Jerry ran into (Sorry!) I wanted to improve
our documentation on how to work with wwwdocs accordingly.  This
patch does not yet address what I believe to be the key point, but
it simplifies the page a bit (removing things that are already
needed for SVN use and some that are not so relevant any more).

Installed.
