and a couple of functions that were missed in the previous batches. Not
terribly tested, but very carefully scrutinized, three times.
All these were found by the little findkrc.py that I posted to python-dev,
which means there might be more lurking. Cases such as this:
long
func(a, b)
long a;
long b; /* flagword */
{
and other cases where the last ; in the argument list isn't followed by a
newline and an opening curly bracket. Regexps to catch all are welcome, of
course ;)

For documentation read the comments in mymalloc.h and objimpl.h.
(This is not exactly what Vladimir posted to the patches list; I've
made a few changes, and Vladimir sent me a fix in private email for a
problem that only occurs in debug mode. I'm also holding back on his
change to main.c, which seems unnecessary to me.)
(1) Use PyErr_NewException("module.class", NULL, NULL) to create the
exception object.
(2) Remove all calls to Py_FatalError(); instead, return or
ignore the errors -- the import code now checks PyErr_Occurred()
after calling a module's init function, so it's no longer a
fatal error for the initialization to fail.
Also did some small cleanups, e.g. removed unnecessary test for
"already initialized" from initfpectl(), and unified
initposix()/initnt().
I haven't checked this very thoroughly, so while the changes are
pretty trivial -- beware of untested code!
otherwise laudible attempt to rationalize the argument parsing): it
would save a copy of the original string instead of a reference to it.
Go back to saving a reference, but keep the "s#" format (using a hack
that involves two argument parsing steps, first using "O", then using
"s#").
- Where optional arguments were being used, converted to
PyArg_ParseTuple() style instead of nested PyArg_Parse() style.
- Check for and handle many potential error conditions that were never
being tested.
- internal reg_* functions renamed to regobj_* (makes it easier to
figure out which are global regex functions and which are for regex
objects).
- reg_group (now regobj_group) was quite extensively reworked. it no
longer recurses to do its job (by factoring core functionality into
a separate function that knows about string and integer indexes).
- some minor formatting fixes.
- regex_set_syntax() now invalidates the cache. Without this change
(in the example below), the second search would produce different
output depending on whether the first search were performed or not
(since performing the first search would cache the compiled object
with RE_SYNTAX_EMACS, causing the second test to unexpectedly fail).
regex.search('(a+)|(b+)', 'cdb')
prev = regex.set_syntax(RE_SYNTAX_AWK)
regex.search('(a+)|(b+)', 'cdb')
