[PATCH] cvsserver: make the output of 'update' more compatible with cvs.

[Sergei Organov <osv@xxxxxxxxx>]

Native cvs update outputs the string "cvs update: Updating <DIR>" for
every directory it processes (to stderr). This is used, e.g., by emacs
pcl-cvs to split files by directory. This commit implements this
feature in cvsserver.
