Hmmm... Okay, there are existing mechanisms for altering the keyword
expansion, so it could be adjusted to trust that of the import. However,
I don't think there are presently any admin functions that twiddle the
execute bits of an existing RCS file, so that will probably need a new
hack.

So, you are suggesting that an import overrite somehow rename the
existing tags? How would an administrator set that kind of policy?
