I am just giving you the point of view of the cvs executable...

Yes, but the VENDOR branch is the default main trunk until such time as
you introduce local changes. From the vendor branch point of view, your
local changes are conflicts in the main trunk that need to be resolved
before the new VENDOR branch will really be visible on the main trunk.

When a new RCS file is created outside of the VENDOR branch, 1.1 is the
first version and the RCS head is 1.1 and there is no 'branch' directive.

When a new RCS file is created using cvs import, the first version is
1.1 as it is always needed, but it is never really used. The is
created as an exact copy of 1.1, the head is 1.1 but a 'branch 1.1.1' is
added to the file. This means that any checkout will pick the 1.1.1.x
version for the largest value of x that is not in the dead state.

A 'cvs commit' of a change to the main trunk of an imported file will
create version 1.2 as head and remove the 'branch 1.1.1' indication.

CVS complained because it saw that the main trun was not using branch 1.1.1
and knows that you must merge the differences of the> into
the main trunk in order to have a consistent main trunk.
