fix broken references to filename var in generateXXX methods

omission noted on c.l.py by Aahz Maruch.

Swapped the order of the descriptions of int() and intern() so that
int() comes first (the functions are in alphabetic order).

Reasons for patches:

1st patch (15,21):
	version change

2nd patch (66,72):
	This is a patch I found in a Zope product release (quite by accident!).
	It relaxes the conditions for matching a literal. I've looked over the
	logic, and tested it, and it seems sensible.

3rd patch (117,123):
	It appears the quoting matcher was too general, and that the IMAP4
	protocol requires characters like ':' in commands to be unquoted.
	(This is the patch already sent to Guido.)

4th patch (699,705):
	Spelling correction in comment.

5th patch (753,761):
	Another patch from the Zope product. It seems that some IMAP4 servers
	produce unexpected responses in the middle of valid command/response
	sequences. This patch ignores the unexpected responses in this
	situation. (How I wish users would send me bug reports with examples!).

last 2 patches: (1015,1028) (1038,1044):
	Minor improvements to test code.

A few alternative selections can be made by changing "if 0" to "if 1".

* Changes to a recent patch by Chris Tismer to errors.c.  Chris' patch
always used FormatMessage() to get the error message passing the error code
from errno - but errno and FormatMessage use a different numbering scheme.
The main reason the patch looked OK was that ENOFILE==ERROR_FILE_NOT_FOUND -
but that is about the only shared error code :-).  The MS CRT docs tell you
to use _sys_errlist()/_sys_nerr.  My patch does also this, and adds a very
similar function specifically for win32 error codes.

(Fred, please check.)

(e.g. used for ZIP files).

The patch includes code that says:
+  Copyright (C) 1986 Gary S. Brown.  You may use this program, or
+  code or tables extracted from it, as desired without restriction.

My interpretation (and Jim's) is that Gary S Brown has no claims under
copyright, patent or other rights or interests.  Lawyers might disagree.

- added a number of support methods to generate code just before the
  body
- hack protocol for communicating number of args to PyAssembler

fix TryExcept generation for case where exception handler has no body
fix visitAssAttr
add comment about incomplete visitAssName

stop using the ExampleASTVisitor

change script invocation to accept a list of .py files (e.g. Lib/*.py)

get the lineno from the name of the keyword arg

example of case that didn't work--
def foo(x, y, a = None,
	b = None):

this is sort of a hack

add support for nodes TryExcept, TryFinally, Sliceobj
fix visitSubscript to properly handle x[a,b,c]

(XXX: the debugger doesn't yet use this.)

it out in a more convenient format than CVS).

messages from "OverflowError: integer pow()" to "OverflowError:
integer exponentiation".  (Not that this takes care of the complaint
in general that the error messages could be greatly improved. :-)
