[CWEB] Restore '\T' macro backward compatibility.
CWEB 4.3 introduced a major change in the '\T' macro to allow C++ 'hex
exponent' notation (e.g., 0x1FFFFp10). This made CWEAVE/CTWILL mutually
incompatible with non-matching versions of their set of macros and v.v.
This change tries to reestablish the standard behavior at least for
numeric constants. Of course, 'old' CWEAVE/CTWILL won't deliver on 'hex
exponents' in the CWEB input, but those should be rare anyway.
