Issue 1951: test_wave.py converted to unittest

In attachment.

Sorry but I realized right now by reading Lib/test/readme.txt that the
test scripts are required to have a global "test_main()" function
defined hence the "main()" function I defined in my patch should be
renamed in "test_main()".

Thanks for the patch!

Glad to help.

Applied in r60602. Thank you very much!

Note that I had to apply the patch by hand... I think that the problem
was in the header: if I get a svn diff, it starts differently than you
patch:

facundo@virtub:~/devel/reps/python/trunk$ svn diff -r 60601
Lib/test/test_wave.py
Index: Lib/test/test_wave.py

I noted that you submitted other patch in other issue, please check that
one to be ok.

Thanks again!!

You're right. It seems that TortoiseSVN generated diff files are
different than using the original svn cmd line tool (probably I'm using
TortoiseSVN in the wrong way).
I'll update the other patches.
