expand is broken bug / don't remove expand though



1. alphalessp is broken. It can easily be fixed. There is a fix.
2. As long as alphalessp is broken, many things are broken. In 
particular, anything that depends on the simplifier.  So it is far more 
than expand.
3. The bug didn't show up previously because it requires upper and lower
case in the same expression to show up.

Making a better alphalessp might speed up the system, too.
