[PATCH] CONTRIBUTE - writing tests for understanding internals

[Przemysław Wojnowski]

Hello everybody,

Here's a small patch that adds to CONTRIBUTE that writing tests is a
great way to learn about Emacs Internals, takes a new contributor
through committing process and is valuable to the project.

Please, check if that has been written in English. :-)

 ** Understanding Emacs Internals.
 
-The best way to understand Emacs Internals is to read the code,

+There are at least two good ways to understand Emacs Internal.

+One of them is to read the code, but the nodes "Tips" and "GNU Emacs
+Internals" in the Appendix of the Emacs Lisp Reference Manual may also

+Another way into Emacs Internal is to write tests. This one is more
+fun, takes you through Emacs contribution process and increases
+Emacs test coverage! Don't think twice!
 
 The file etc/DEBUG describes how to debug Emacs bugs.
