Actually, make dist throws up some other errors too, which are probably additional obsolete filenames:

Looks like at least some of them date from 7e758423f8189769448509c51add7f73118a4158. I'll check the list from scratch.

I've pushed an update that removes obsolete filenames from the list and adds some that were missing. make dist now works, although I'm not sure how useful the produced tarball is nowadays.

We should update the PR title/description to reflect the wider scope of the changes.

Thanks.

Why is this 3.12.0 and not 3.11.0? Given that it's fixing something that's incorrect, and doesn't affect the application code or translations.

We're just conservative on tagging things after freeze.

Anyway, retagged
