The vendor branch more closely models the RCS
branching model. The initial import creates
version 1.1 of a file and then 1.1.1.1 immediately
afterward while at the same time changing the RCS
branch to '1.1.1' and laying down a vendor tag label
on the '1.1.1' RCS branch and the vendor version tag
gets put onto 1.1.1.1.

So, an imported version is always a real RCS branch.

A cvs 'magic' branch has a tag name associated
with a 'number' that looks like the base version
of the file followed by the magical '.0' followed
by an even number selected after looking at the
other CVS 'magic' branch tags in the file.

This 'magic' branch does not actually consume any
delta record space in the RCS file until after you
make a commit to the branch. This is also known as
doing a 'lazy' allocation.

Mostly it is where the RCS view of the file
collides with the CVS view of the world...

If you really want to read more details, you
probably need to dive into the doc/RCSFILES in one
of the CVS releases and then read up in Cederqvist
on "RCS History" and "RCS, importing files from" ...

You may also find it helpful to read
http://cvsbook.red-bean.com/cvsbook.html
(although I can't recall how deeply Karl covered
import and vendor related stuff in his book).

Yeah, I can understand that point of view too. :-)
