Finding vhdl-mode.el (because that's large) and then doing M-:
(jit-lock-mode nil).

Yes.  So I did that and found vhdl-mode.el again.  Nothing is fontified.
(font-lock-flush) doesn't change that, but (font-lock-ensure) fontifies
the complete buffer.

That's a good plan.  :-)

So Daniel and Drew, feel free to complain about concrete macros.  Or
just add a (declare (no-font-lock-keyword t)) to them yourself.

Oh, cool.  Is that going to be an alternative to `defsubst' or is the
plan to make it `defsubst' at some point in time?  (At least from a very
brief look, it seems to provide the same interface for the same
use-case.)
