It's the other way around in fact.  admin is a last resort when you really
must delete a revision (for example for legal reasons or more mundanely if
a binary file is getting too big).  It physically deletes that information
from the RCS file, which is bad for tracking.

If you simply re-add the file it gets a new revision and the 'delete' is
kept, too, so you can recover the state of the repository when the file was
there, when it was deleted, and when the new file was added.  You can also
have a file that's deleted on one branch and active on another (happens a
lot when you're working on release/development branches simultaneously).
