Can we add another row, saying "the previous row was inaccurate"?  I
guess that would break parsers also.



I don't know if this was by design, but the present format does provide
extensibility.  It is basically

	NNNN NNN name:value name:value

one could arguably append a third name:value and hope that authors of
existing parsers figured this out.


Whatev.  I'll drop this version from mm.git.
