Does rdiff miss new files?

[Duncan]

Hello all,
I've seen this same question asked here a few times before but with no
responses so I'll throw my hat in the ring and ask yet again.  Does
rdiff miss newly added files that exist in only in one
tag/branch/version but not the other?  I created a branch, added and
commited 2 new dirs full of files, then did a:

cvs -Q rdiff -f -s -r HEAD -r APT-PROJECT-BRANCHED-2-25-02 intranet 

And got no output.  Is this the standard behavior of rdiff?  If so
this is a bit of a bummer as the main thrust of what I want to do most
of the time is to see and integrate new development into the main
line, not just new revisions of existing files.

Any thoughts or alternatives?  Is this just me?
