  Changed paths:
    M m3-sys/m3front/src/values/Formal.m3

  Log Message:
  -----------
  Refactor parameter passing.

This is a pure refactor.

It was very confusing, with multiple paths merging, then diverging
again, based on different tests of some of the same conditions on
the first divergence.
