userdiff-cpp: permit the digit-separating single-quote in numbers

Browse Source 
Since C++17, the single-quote can be used as digit separator:

   3.141'592'654
   1'000'000
   0xdead'beaf

Make it known to the word regex of the cpp driver, so that numbers are
not split into separate tokens at the single-quotes.
