[Cvsnt] Branches and tags lost in the repository

[Sergei Chernov]

A small addition:

I am using a fairly simple subset of CVS commands:
    checkout (sometimes with -r)
    log -r
    rtag
    update (sometimes with -C, -P, -d) and commit in their simplest form,
mostly from WinCVS.
I never merge cvs branches.
