You needed to add '-b vendor/sendmail' here for it to create a branch in
your local name space (not in the freebsd/* upstream namespace).

Yea, the -b was missing above, I think.

Yes. You've not created a vendor/sendmail branch yet, so there's no 'ref'
to push. This message really is git saying 'I'm not sure I know what
vendor/sendmail is', since it uses that to know what to push upstream. This
is where having the upstream set correctly just might matter.

If you look in your config file, you should see something like:

It's better done with the above -b command so that the 'upstream' is set
right (though this might not be one of the times that matters).

I think it will, but it won't have the upstream as freebsd/vendor/sendfile
which would be a problem if anybody else ever committed to that vendor
branch (or he did on a different machine).

[branch "vendor/sendmail"]
        remote = freebsd
        merge = refs/heads/vendor/sendmail

in the .git/config file from the repo (I hacked that together off a machine
I think has the right entries)

Yea, git makes it stupidly easy to throw away work that's somehow done
incorrectly the first time...
