I fixed the input parsing stuff so that it's possible to input digits
A to Z in bases greater than 10 decimal. (Digits 0 to 9 were
recognized in the assigned base, but not A to Z.)
However A to Z are recognized only if the leading digit is 0 to 9.
Otherwise it's recognized as a symbol. That preserves ordinary
function names and variables. I made a corresponding change
to the display code so that displayed numbers are readable as
such, therefore they have a leading 0.
? ibase and ? obase state the current policy.
