  Add remove_path: a function to remove as much as possible of a path
  git-submodule: Fix "Unable to checkout" for the initial 'update'
  Clarify how the user can satisfy stash's 'dirty state' check.
  t4018-diff-funcname: test syntax of builtin xfuncname patterns
  t4018-diff-funcname: test syntax of builtin xfuncname patterns

  diff: fix "multiple regexp" semantics to find hunk header comment
  diff: use extended regexp to find hunk headers
  diff: use extended regexp to find hunk headers
  diff.*.xfuncname which uses "extended" regex's for hunk header selection
  diff.c: associate a flag with each pattern and use it for compiling regex
  diff.c: return pattern entry pointer rather than just the hunk header pattern
