That depends upon your definition of "correct". The svn ci
documentation states "Send changes from your working copy to the
repository." and directories which are created by svn:externals are a
separate WC from the parent.

I think TSVN commits the externals as a separate commit from the
parent directory (which it must, because the external is a different
WC), but does it all in one shot for you. The command line client only
commits a single WC. You could script it to do what TSVN is doing
though.
