Merge branch 'js/userdiff-cpp'
Userdiff patterns for the C++ language has been updated. * js/userdiff-cpp: userdiff-cpp: back out the digit-separators in numbers userdiff-cpp: learn the C++ spaceship operator userdiff-cpp: permit the digit-separating single-quote in numbers userdiff-cpp: prepare test cases with yet unsupported features userdiff-cpp: tighten word regex t4034: add tests showing problematic cpp tokenizations t4034/cpp: actually test that operator tokens are not split
