[cvsnt] Bug report: update fails on XP for empty XXX and full xxx directories

[Miklos Maroti]

CVS client: (CVSNT) 2.5.03 (Scorpio) Build 2382

If you update a module that has an XXX directory that is empty (and is
automatically pruned at checkout) and another one called xxx that
contains data, then the update fails saying that some files are in the
way (probably when it wants to prune the empty directory). You can
very easily reproduce the bug by checking out the following repository
and updating it immediately:

CVSROOT: :pserver:tinyos.cvs.sourceforge.net:/cvsroot/tinyos
REPOSITORY: tinyos-2.x

Best,
Miklos
