Currently, the git diff hunk headers show the wrong method signature if the
method has a qualified return type, an array return type, or a generic return
type because the regex doesn't allow dots (.), [], or < and > in the return
type. Also, type parameter declarations couldn't be matched.
Add several t4018 tests asserting the right hunk headers for different cases:
- enum constant change
- change in generic method with bounded type parameters
- change in generic method with wildcard
- field change in a nested class
