Nikita Popov a2443aaefa Make check in numeric literal separator emulator more precise ...

a) Don't check for !== false, preg_match() return 0 if there is
no match. This effectively means that the check was always true.
b) Check for hex characters only if there's an 0x prefix. 1_1 is
very likely a numeric separator, but a_b might well be part of
an identifier.

Fixes #639.
