I like the general idea of this, but I think it should be structured thusly:

- move all the details of testing gendoc into a helper script
- make each language-specific test a trivial one command call and its output:

  $ TESTDIR/check-gendoc da
  checking for parse errors

  (without using hg cp)
- reduce the test-gendoc.t loop to checking there's a test for each language

This way, if we ever make changes to check-gendoc, we don't have to
remember to manually copy it to all the tests.

One benefit here worth mentioning is translators only need to run the test for
their language.
