of the current module.  It also runs the tabnanny to catch any
inconsistent tabs.

Also did a little bit of refactoring: added an errorbox() method to
simplify the display of error dialogs.

PyEval_EvalCode() is *not* a "backward compatible interface", it's the
one to use!

enough, it could be negative.  Add i > 0 test.  (Not i >= 0; zero isn't
a valid error number.)

Added FreeMem, MaxBlock and CompactMem calls. The values returned by these are lower bounds in the Python case (as malloc doesn't return memory to the heap) but they can be used to decide when to give low-memory warnings.

	The same problem (mixed mallocs) exists for the pcre stack.
	The buffers md->... are allocated via PyMem_RESIZE in grow_stack(),
	while in free_stack() they are released with free() instead of
	PyMem_DEL().

	The buffers self->regex and self->regex_extra are allocated in
	pcre_compile() and pcre_study() via pcre_malloc, but are released
	via free() instead of pcre_free.

  add clsFilesystemImporter class attribute, alter handling of suffix list
convert suffix importers to funcs rather than instances
remove backwards compat code: Importer.install and 2-tuple get_code()
  result values

switch to isinstance() rather than direct type comparisons
removing chaining concept
update ImportManager.install() to take an optional namespace to install
  itself in. this will be useful for setting up rexec environments.

in 'find_command_class()' method.

command itself: no more of this "FooBar class for foo_bar command"
silliness.

old 'dist' command, but the code for dealing with manifests is completely
redone -- and renaming the command to 'sdist' is more symmetric with the
soon-to-exist 'bdist' command.

- removed now (happily) unused second arg
- need to verify results of [].index are correct; for building consts,
  need to have same value and same type, e.g. 2 not the same as 2L

(big surprise).  new solution is a little less hackish.

Code gen adds a TupleArg instance in the argument slot. The tuple arg
includes a copy of the names that it is responsble for binding.  The
PyAssembler uses this information to calculate the correct argcount.

all fix this wacky case: del (a, ((b,), c)), d
which is the same as: del a, b, c, d
(Can't wait for Guido to tell me why.)

solution uses findOp which walks a tree to find out whether it
contains OP_ASSIGN or OP_DELETE or ...

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
