This is kind of my point. If someone calls ido-completing-read, you
wouldn't expect it to do something different based on the value of
completing-read-function, even if it ido used completing-read internally
(which it might have actually done in the past, but currently does not),
because by calling ido-completing-read the code has already specified it
wants ido completion. Similarly, tmm is implementing a very different
behavior from completing-read that is only recognizable as regular
completion if you specifically go looking for leaks in the abstraction, and
for the same reason I don't think tmm should be paying attention to
completing-read-function.
