 From a copy of the manual[1], I think you want to use one or two "-j"[2] 
options with update. I don't think the -j merge will remove files[3] just 
because there is no tag on some files, but it may.  You may be stuck using the 
implicit Date tag, i.e., figure out where in time you want to revert to and 
use "update -D"[2] with the understanding that you will likely have a sandbox 
with a sticky tag, however this can be useful to finally apply that tag to the 
whole tree instead of just a few files.

In the end you will probably be happier when you learn to "tag the whole tree 
not just a few files" in the beginning. :) (Sorry, but it is generally true.)
