[PATCH 7/7] cvsserver: Use the user part of the email in log and annotate results

[Damien Diederen <dash@xxxxxxxxxx>]

Generate the CVS author names by taking the first eight characters of
the user part of the email address.  The resulting names are more
likely to make sense (or at least reduce ambiguities) in "corporate"
environments.
