These are all fixed now, thanks Thomas!
OK, so one more thing. In the wiki page about this area:
"Note that there can be multiple levels of translation-check headers
chaining through different files, for example:"
Thinking about this, that's actually irrelevant to this work. I *can*
track through a chain of dependencies here (tedious, but possible -
may potentially involve checking out different versions of files from
git), but I really don't think we need to at all. Feel free to try and
convince me otherwise!
Initial script attached.
Checking the git diff output after running the script without
--dry-run (i.e. making changes), I can see a few more files which I
think look bogus for their translation-check metadata. They've all got
multiple translation-check lines in the header, with (maybe?)
conflicting data:

For the sake of 5 files, I'm tempted to (again) just fix up the
metadata in CVS to remove any amiguity here.
