Thank you, Phil: that certainly is.

Also, I'd like to stress one thing I mentioned earlier on in this thread
(and had completely forgotten about!), *just in case* it might be
important:-

Although admittedly it doesn't make much sense to load tipa without loading
xltxtra or xunicode as well, if you just load fontspec [v2.1] (*and* tipa,
of course), you still get the extra trailing space with the \textipa
command, and this because —I believe— fontspec invokes \scantokens, too. So
xunicode's behaviour is "consistent" in that it preserves fontspec's
behaviour. :-)

Therefore *maybe", whatever approach is used to address this bug, the same
"fix" should be applied to fontspec, too...?
