Ahh, right, thankyou make, for reminding me that 'all' isn't actually
any automagically chosen target that is chosen when no target has been
specified. No, instead, the first target is chosen.
And not just any target! Only the first non-templated target is chosen,
so in this case: po/telegram-purple.metainfo.xml.pot .
However, in our case that's utterly pointless, so 'all' needs to
be on top again. I should have known there was an important reason.
