[PATCH] t4018: add a few more test cases for cpp hunk header matching

[Brandon Casey <casey@nrlssc.navy.mil>]

From: Brandon Casey <drafnel@gmail.com>

Add one case for matching a function returning a pointer.

Plus add examples of things we explicitly do not match:

   labels
   function declarations
   global variable declarations

Signed-off-by: Brandon Casey <drafnel@gmail.com>

This can be squashed into the original patch with the other test cases.
This just introduces a few more cases pointed out by Thomas Rast in the
email Johannes referenced.

   http://thread.gmane.org/gmane.comp.version-control.git/186355/focus=186439

Also, note that all of the tests pass except for ignore_global.cpp with
Johannes's pattern:

   "!^[ \\t]*[a-zA-Z_][a-zA-Z_0-9]*[^()]*:[[:space:]]*$\n^[a-zA-Z_][a-zA-Z_0-9]*.*"
