[PATCH 00/10] userdiff: cpp pattern simplification and test framework

Here is a series that makes the hunk header pattern for C and C++ even simpler than suggested by Peff in [1] to catch a lot more C++ functions and two more C patterns.

As a preparatory work, the test cases are totally rewritten to make it a lot simpler to drop in new tests. There was an earlier attempt to change the infrastructure [2], and it is the reason for the widened Cc list.

Two patches also extend the word regexp.

Johannes Sixt (10):
  userdiff: support C++ ->* and .* operators in the word regexp
  userdiff: support unsigned and long long suffixes of integer constants
  t4018: an infrastructure to test hunk headers
  t4018: convert perl pattern tests to the new infrastructure
  t4018: convert java pattern test to the new infrastructure
  t4018: convert custom pattern test to the new infrastructure
  t4018: reduce test files for pattern compilation tests
  t4018: test cases for the built-in cpp pattern
  t4018: test cases showing that the cpp pattern misses many anchor
    points
  userdiff: have 'cpp' hunk header pattern catch more C++ anchor points
