[PATCH 0/3] Fun with cpp word regex

The cpp word regex driver is a bit too loose and can match too much text where the intent is to match only a number. The first patch fixes that.

The other two patches add support for digit separators and the spaceship operator <=> (generalized comparison operator).

I left out support for hexadecimal floating point constants because that would require to tighten the regex even more to avoid that entire expressions are treated as single tokens.

Johannes Sixt (3):
  userdiff: tighten cpp word regex
  userdiff: permit the digit-separating single-quote in numbers
  userdiff: learn the C++ spaceship operator
