Just to make it clear: as Martin explained, the main issue here is
that TortoiseHg uses the main instance of Launchpad to manage its
translations. And according to the FAQ, launchpad.net demands that all
those strings are licensed under the 3-clause BSD license. My question
(and my translation work) simply assumed this was OK.

My understanding is that a work derived from a GPLv2 work must be
*available* as GPLv2, so a BSD translation would qualify (the combined
work (Mercurial + translation) will surely be available as GPLv2,
since the translation license is compatible).

I understand that legal issues sometimes don't follow logic, but I got
this interpretation from the following FAQ item:

http://www.fsf.org/licensing/licenses/gpl-faq.html#CombinePublicDomainWithGPL

That suggests a GPLv2 work could include parts available under
different licenses (and fwiw, I do understand that "public domain"
isn't a license).

Also, in my country translations themselves are considered creative
works, so I may choose another (additional) license for *my
translation work itself*. That may be useless in itself (depending on
how exactly the original work restrict the distribution of a
derivative work *by itself*), but it would matter if for example the
original work is relicensed, or if the translation could be reused in
another context.

Anyway, I got my answer :-)  Thanks for your clarifications.
