update -j -j gets unwanted files

[Jacob Weber]

I have a directory on the main trunk, whose files were tagged at one point
in the past. Now I am working in a branch, and I would like to revert that
directory to the tagged version. I want to be able to commit this change to
the branch, so I don't want sticky tags.

This is what I tried:
cvs checkout -r branchName project/dir
  (to get the latest version of the directory on the branch)
cvs update -j branchName -j tagName
  (to revert the changes)

For the tagged files, this gets the right versions. The problem is, this
also pulls down files that were added to the trunk after the tagging. These
files have no tags, but they were still retrieved in the update. I would
expect this behavior if I passed -f to cvs update ("Force a head revision
match if tag/date not found"), but I didn't (and it's not in my .cvsrc
file).

Any idea why? Thanks,
Jacob
