[PyQt] dynamically determine if in a macro?

I don't believe so. isClean() refers to whether the current command index is
at zero. If I push a command, then begin a macro, isClean will always
be False. Your logic only works if the macro is the first command, which in
general isn't true

Again, I don't think this is correct. Index() increments and decrements with
calls to redo/undo and has nothing to do with the count(). I don't even believe
that when in a macro, the count increases until the macro is done.
