I used your excellent idea to find the directories in which I had files
with erroneous revision tags. I then used this large-axe-approach:

    $ cvs log -l | egrep '^Working' | while read a b c
    >do
    >cvs tag -d forv_ver1_020311-branch $c
    >done

First I get the log for all files that ever existed in the current
directory (the -l switch). I then grep for "Working" thus getting a
string with contains, amongst others, the file name. This string is a
bit hairy and I was to lazy to fiddle with cut so I resorted to feeding
everything to read: a is always set to "Working", b to "file:" and c to
the current file name.

I then delete the tag from the file (cvs tag -d). Since the file does
not exist in the branch and has the branch tag as a revision tag is this
safe to do. Furthermore: all files that are correctly tagged with the
branch tag will survive this assault with an error message instead.

Thus: all files with the branch tag as revision tag got it removed; all
other files are left untouched. QED.

Scary, but it worked. Nothing for the faint of heart :-)

Thanks, everyone!
