To clarify with what Bruce said on IM to me, the situation is when the
workflow is to manually copy a file from one repo to another before
committing (a working one vs the committer one for example), it may
not be up to date on the version id. Personally this never happens
because I move files by making "cvs diff" in one and applying in the
other, not copying the files.

For one thing, this showed up in a lot of .po files for 8.1.0RC1.
Peter, can you comment on if this coincides with the tools you use to
do those things?

Yeah, but do we want to? It means a git checkout of the branch tip
will be slightly different - in keywords only - from the previous
checkout in cvs.
