Yes, it reformats the equation as if the implicit () was on, but that changes
the semantics of the equation quite a bit.  It shouldn't be doing that, IMHO.,
but rather should be leaving the part of the equation alone that had been set
with implicit ()'s off.  In fact, I venture to state that it should NOT be
reformatting the equation at all when I press the <- key.  The equation is
as I want it, else I'll delete it myself, thank you.
