Nope. It has no real way to tell when it should change the cursor.
If you allow the user to let the OS draw the cursor, then I think you
should also allow them to change its shape, since that is a trivial thing
to do anyway. Otherwise, we will probably be getting feature requests for
it anyway and adding that functionality afterwards will only clutter up the
API more. ;)

I disagree. What if you actually want to hide the mouse cursor temporarily
for whatever reason (displaying a cinematic sequence, say)? Hardware mouse
mode is like normal mouse mode, but with the OS drawing the cursor rather
than Allegro. Call select_os_cursor() after show_mouse(NULL) if you want
the default one. This change would also break the API, since the behavior
of show_mouse(NULL) has always been to hide the mouse cursor in either soft
or hardware mode.
