I don't remember why, but that patch didn't get enough interest

If you care enough about this scenario, how about search for the
relevant <CVSROOT, password> in both files. If you find just one pair or
if you find a pair in both files and they are "equal" then just use it.
If you find two pairs, one in each file, use the one from the file with
a newer modified time-stamp. In a migration scenario such as this, you'd
imaging the "old" file will get stale after a while. Not perfect, but
some informational messages in case of a duplicate would help the user
clarify their intentions

Additionally/Alternatively just add a command line parameter to allow
the user to explicitly specify a cvspass file


Cheers,
Emil.
