[PATCH] cvsserver: Fix handling of diappeared files on update

[Frank Lichtenheld <frank@lichtenheld.de>]

Only send a modified response if the client sent a
"Modified" entry. This fixes the case where the
file was locally deleted on the client without
being removed from CVS. In this case the client
will only have sent the Entry for the file but nothing
else.

 We really, really need a test suite for cvsserver...
 I've tested this as good for regressions as I could
 think of but am still unsure about it.
