The first three patches are some fixes/improvements to the asciidoc
documentation. Just some random stuff that I noticed while working
on git-cvsserver.

The forth one is a good example how much CVS actually sucks
regarding data security and deterministic behaviour.

All of these should be suitable for maint.

The fifth is a small feature enhancement for git-cvsserver. It
adds support for 'cvs login' over pserver.

I think this is trivial enough to go to master directly, but feel free
to let it rot in next first.
