Summary: ast-branch: multiple function fixes
Initial Comment:
This patch fixes:
- handling of keywords, varargs, and kwargs on function
definition
- handing of keywords, varargs, and kwargs on function
call
- handling of keywords for lambdas
- function chaining (foo().bar().baz())
Applying this uncovers some another bug that at least:
- cause a core dump upon import of sre_parse
- cause an infinate loop upon import of ntpath
I believe I've tracked down the problem to the
generation of bad bytecode for nested loops, as in:
for x in 1,2:
for y in 3,4:
print x,y
This causes problems with Subpattern.dump() in
sre_parse and ntpath's commonprefix().
I'll try to figure out what's wrong with nested loops next.

Almost all of this has been checked in by Jeremy. I'm not
sure if he took it from the patch or not. There are only
two small changes that look like they haven't been applied.
Attached is an updated patch.
The updated patch fixes a problem when MAKE_FUNCTION on a
lambda. It always used the len of args, rather than the
length of defaults. The other fix is for calling a func
with **kwargs. The # args never included the kwarg count.
