I'm not sure I understand the reason for this elaborate setup.  It
sounds like CVSROOT is in ~/tmp1, but you expect Emacs to understand
that ~/tmp3/project1, which is outside of the ~/tmp1 tree, is part of
the CVS repository in ~/tmp1?  Why is the correct expectation?

FWIW, "C-x v d" in a CVS repository (i.e. a directory which has a
'CVS' subdirectory) does not signal an error, and displays the correct
VC status of the files.

Please tell how Emacs was supposed to realize that ~/tmp3/project1
directory is a CVS repository.

Thanks.
