OK, good. Any obvious problems with that solution? I don't work with CVS 
at all, and if you (or anyone else) interact with any particularly big 
repositories, I'd love to hear how it fares there.

That's too bad. I've tried the patch myself, and I didn't see those, 
neither with the temporary repository created using Göktuğ's 
instructions, nor with a random GNU CVS repo I cloned afterwards.

Might there be something special with the repo you're trying it on? 
Maybe the fact that the working dir and the repository root only have 
the root directory as the common ancestor? Just a random guess.

Agree, that doesn't sound like too big of a problem.

And seeing unregistered files is pretty much working as intended. Alas, 
I see them in both versions of the code (the one using `dir', and the 
one using 'cvs update').

Any ideas why you're seeing differently? Do you have a non-default value 
of vc-cvs-stay-local, maybe?
