there is actually no reason to expect Maxima to "simplify" an expression to
some arbitrary form that you happen to like;
Maxima has its own particular repertoire of "kinds of simplifications" and
getting exactly the ordering you want may be contrary to its rules. On the
other hand, there is a package that tries to come up with a formatting
arrangement that might allow for something like this form. Bruce Miller
wrote it, and it is called format. e.g. load(format) does it.
