Right.  Was there in fact a 'mlym' spec ever?  IIRC Malayalam was added when
the new specs were designed.

At any rate, you need to add a 'pref' table to the font that matches the
sequence 'Ra,Halant' (for 'mlym') or 'Halant,Ra' (for 'mlm2').  You add that
and the font works.  We are not going to work around this.
