and #103717.

Guido told me to do this <wink>.
Greatly expanded docstrings, and fleshed out with examples.
New std test.
Added new get_close_matches() function for ESR.
Needs docs, but LaTeXification of the module docstring is all it needs.
\CVS: ----------------------------------------------------------------------

create an empty dictionary if it is called without keyword args.  Just
pass NULL.

XXX I had believed that this caused weird errors, but the test suite
runs cleanly.

functinos and cell vars with */** parameters

Remove to XXX comments

of nested functions.  Either is allowed in a function if it contains
no defs or lambdas or the defs and lambdas it contains have no free
variables.  If a function is itself nested and has free variables,
either is illegal.

Revise the symtable to use a PySymtableEntryObject, which holds all
the revelent information for a scope, rather than using a bunch of
st_cur_XXX pointers in the symtable struct.  The changes simplify the
internal management of the current symtable scope and of the stack.

Added new C source file: Python/symtable.c.  (Does the Windows build
process need to be updated?)

As part of these changes, the initial _symtable module interface
introduced in 2.1a2 is replaced.  A dictionary of
PySymtableEntryObjects are returned.

hooks to take over the Python import machinery at a very early stage
in the Python startup phase.

If there are still places in the Python interpreter which need to
bypass the __import__ hook, these places must now use
PyImport_ImportModuleEx() instead. So far no other places than in
the import mechanism itself have been identified.

Replaced touched(), which no longer seems to work under os9, with something using an appleevent to the finder. More expensive, but at least it works:-)

spaces->tab conversion for fields added to struct compiling.

Some of the characters (form feed, vertical tab) are not
legal continuation characters anyway, so this was wrong as
well as annoying.

(This one was trivial -- no actual string. references in it!)
