OK. The invention of yet another global flag is a little
disconcerting, but there is ample precedent for it ....
Also I wonder if such a thing (whether a flag or a function)
should be named expand_beta instead of beta_expand.
It appears that foo_expand is more common in Maxima
than expand_foo, so, again, I guess beta_expand is more
harmonious with existing stuff.

Agreed.
Thanks a lot for working on this!
