Better to split the refactoring part of this into a leading
change. I.e. the latter 2 removed/2 added here, and the former could
also start with a wrap to 79 chars...

Ditto this 4 space -> tab change.

This patch of mine didn't end up making it in, but shows how instead of
"tag, tag, tag" here you can just pass it once and use positional printf
arguments in the message. It makes things a lot more self-explanatory:

At least some of these tests should change the existing test line to a
"test_must_fail", i.e. assert that without the new option these aren't
created, maybe for good measure test --force too.
