I agree.

OAUTHDEBUG_LEGACY_UNSAFE?

I think I'm missing something; how does the choice of .c/.h change
things? There's no static tracking in v1 of the patchset (nor should
there be without locking or atomics, which is not maintenance I really
want to introduce for a debug feature).

Which new corner cases? v1 also prints duplicates (e.g. with
`UNSAFE:blah,http`). I didn't intend to introduce any new calls to
oauth_get_debug_flags() over those already done in v1/v2; if I did
that's a bug.
