[BUG] cvsserver triggers (probably harmless) cvs warnings

Something I just observed during git-cvsserver tests but which I don't have the time to track down right now:

If during "cvs update" a new file is sent in a subdirectory of a subdirectory which both don't exist, this triggers a warning from the CVS CLI client:

Example: cvs update: warning: server is not creating directories one at a time U board/westel/amx860/Makefile

(where boards/westel and board/westel/amx860 both didn't exist before).

Doesn't seem to do any harm but perhaps someone has more time and motivation than me to fix this annoyance :)

Gruesse,
