You are right, it is a bug in groff's MM.  Your fix does look
reasonable.  The real problem is that groff's MM's treatment of
displayed equations is messed up, and should be completely reworked.
In groff's MM the equation number is printed independently of the
equation proper, and is thus not guaranteed to be aligned with the
baseline of the equation.  AT&T MM does it correctly.
