Hi again,

I've fixed the bug I reported below yesterday.  The ChangeLog entry
and patch against cvs-1.11 are attached.  Please let me know if you
need anything more.

        * checkout.c (build_one_dir): Fix typo where clauses of two
        conditionals were reversed in call to Create_Admin.  This caused
        the CVS/Tag file to be removed in cases where it should have been
        set, and vice-versa.  It only surfaced in rare cases as this code
        is only invoked when using the -d option to build the path to
        check out in.  Further, the bug would only matter when checking
        out a module containing ampersand modules within it, via
        client/server CVS.
