I think I understand the issue now: it happens inside
Man-completion-table, right?

But then I don't understand the situation: why would someone type
"M-x man RET 2 ", with the trailing space?  Is this simply a mistake
on behalf of the user?

Stefan, any ideas how we can catch this situation?  I don't think we
can blindly remove the trailing whitespace, since this could be
meaningful in completion?
