--- Comment #2 from Steven Schveighoffer <schveiguy at yahoo.com> ---
Thanks! Ironically, the original fix was added to "fix" ddox. And now I'm
encountering this bug in ddox.

I think there seems to have been a discrepancy in ddoc vs. the json output, but
the fix seems to be overzealous.

I'll see if I can play with it to figure out the right balance, but I might
need help.
