[PATCH maint 2/2] t4018-diff-funcname: demonstrate end of line funcname matching flaw

[drafnel@gmail.com]

Since the newline is not removed from lines before pattern matching, a
pattern cannot match to the end of the line using the '$' operator without
using an additional operator which will indirectly match the '\n' character.

Introduce a test which should pass, but which does not due to this flaw.
