What he said!
Note that if all of these conditions are met except the last one,
ie. the ,v file has an appropriate vendor branch, but the latest
revision on that branch is marked "dead", then of course the new
release tag should be added to that dead revision -- as happens
now for an unchanged "live" file.

This is the only part I question -- and I do mean "question"; I'm
not asserting that it's wrong, but wondering whether it might be,
and asking people to think about it.
Should this be based on the import branch number, rather than
name? That is: if, in the above example, branch-tags "vendor1"
and "vendor2" both referred to branch 1.1.1, then they'd be
considered identical for this purpose; vendor2_file1 *would* be
deleted during the "third" import. But if "vendor1" and
"vendor2" referred to different branches, eg. the vendor2 import
had been:
$ cvs import -m second -b 1.1.3 tst vendor2 vendor2_v1
then, as Nathan says, vendor2_file1 would *not* be deleted during
the "third" import -- indeed, in this specific case, it wouldn't
have to be deleted, since it wouldn't be on branch 1.1.1 in the
first place.
But perhaps that's what Nathan meant by:
> AND that branch has the same version as the branch version specified

in which case, all I'm questioning is whether the following
condition should go away:

With sufficient thrust, pigs fly just fine. However, this is not
necessarily a good idea.
