I myself do not have the time to look into problems in the shipped
macro packages at this moment (I never use those mnacros personally,
so I am not the best person to work on them, either). I have to leave
it up to someone else with a bit of free time and knowledge to work
on the problem(s) and post a fix.

Every bugfix that is available and passes some simple Q & A tests
will be included, of course.

That one will be included.
