lilypond and python-2.2

[Petr Mladek]

Hello,

I had problem to compile lilypond-1.4.10.tar.bz2 with new
Python-2.2.tar.bz2.

You already found the critical line in lilypond-book.py:
# pyton2.2b2 barfs on this
                 'lilypond-block': 
r"""(?m)^(address@hidden)(?P<match>(?s)(?P<match>@lilypond(\[(?P<options>.*?)\])?\s(?P<code>.*?)@end
 
lilypond\s))""",


I found the equivalent code in python and a new check was added there.
I think that the pattern for reqular expresison can not contains 
the same identifier <match> two times. And this bug is checked now
by python. It is correct and logical.

Small patch is attached. lilypond-book.py works now. Unfortunateely I have 
not assurance that the fix is correct.
