cvs update: move away xyz; it is in the way

[Chad Loder]

Hello. I'm getting inexplicable messages when updating
my CVS sources:

cvs update: move away foo.c; it is in the way

where foo.c is a file that's still in the archive,
whose sandbox version is up-to-date w.r.t. the repository
version, and so on...I've never touched the thing.

I saw some posts in the mail archives about this sort
of thing, with some responses giving implausible
explanations. :)

What should I be looking at, if I really want to know
what's causing this and how to stop it.

Thanks,
        Chad Loder
