More consistent handling of radix letters

Allow any radix letter from the set [bydtoqhx] to be used either
"Intel-style" (0...x) or "C-style" (0x...).  In Intel style, the
leading 0 remains optional as long as the first digit is in the range
0-9.

As a consequence, allow the prefix "0h" for hexadecimal floating
point.
