Behaviour of \latinfamily

IIRC, this switch is called \if_fake_narrow.  It is never changed by fontinst
itself, but there is a macro \fakenarrow{WIDTH FACTOR} to change it.

Yes.  The `mb' designation was my idea, since it was inappropriate to
map both 'r' nad 'm' to the same code.  Presumably, it was mistake that
NFSS codes used 'm' for regular in the first place, but it's too late
to change it now.

Cheers, Ulrik.
