Removed the entire __name__ == '__main__' block.

Modified string.split documentation to reflect behaviour of splitting emtpy string.  Closes SF bug #811604

NULL in case of error, but the functions are declared to return int.
MSVC 6 properly complains about that.  Return -1 on error instead.

Gives 30% speedup on "a,b=1,2" and 25% on "a,b,c=1,2,3".

custom importers.

Fixes bug #883604 .

Change %08l to %p to print a pointer.
Will backport to 2.3.

'a.extend(a)' isn't so special anyway.

I've been bitten by this myself in the past half year.

I'll backport this to 2.3.

UNTESTED!!!

This simple two-line patch has been sitting on SF for more than 2 years.
I'm guessing it's because nobody knows how to test it -- I sure don't.
It doesn't look like you can get to this part of the code on Unixish
or Windows systems, so the "how to test it?" puzzle has more than one
part.  OTOH, if this is dead code, it doesn't matter either if I just
broke it <wink>.

all whitespace at the end of the path line.

Removed Win9x notes (since the .NET compiler requires Win2K or XP anyway).

parser -- for now. Failure behaviour of the new parser(s) will change in any
case, so this will be revisited later anyway.

HMAC.__init__().  Adapted from SF patch 895445 "hmac.HMAC.copy() speedup"
by Trevor Perrin, who reported that this approach increased throughput
of his hmac-intensive app by 30%.

new pattern for NEXTARG() is detected and optimized as a single (*short)
loading.
