Fix bogus error return when open_osfhandle() doesn't have the right
argument list.

Tkinter.  This adds a separate lock -- read the comments.  (This was
also needed for Mark Hammond's attempts to make PythonWin
Tkinter-friendly.)

The changes have affected the EventHook slightly, too; and I've done
some more cleanup of the code that deals with the different versions
of Tcl_CreateFileHandler().

Particles break out of their loop when the main loop exits.

- Handle <? processing instructions >.

- Allow . and - in entity names.

Also fixed an oversight in the previous fix (in one place, [ \t\r\n]
was used instead of string.whitespace).

so that our #ifdef test has the wrong effect.  Substitute hardcoded
values for some important symbols (but not for the whole range -- some
are pretty obscure so it's not worth it).

control before TrackControl is called. The default implementation
calls TrackControl and then do_controlhit().

For ScrolledWindow, do_rawcontrol passes a tracker function to
TrackControl if the mouse is in one of the arrows or grey areas, and
the tracker handles scrolling. For the thumb part nothing has changed.

TrackControl. TrackControl is now manually generated (too much work to
explain this to bgen).

walks and quacks like a dictionary.

we are threading, otherwise accessing errno doesn't work right.

Revert to using whrandom so it will work with older versions of Python.

sys.maxint and near -sys.maxint-1 work correctly.

Guido, the overflow checking in PyLong_AsLong is off a little:

1) If the C in use sign-extends right shifts on signed longs, there's a
spurious overflow error when converting the most-negative int:

Also, here is a new version of import_nt.c, which allows you to register a
Debug module in the registry.  While I was there I removed some of the
ugliness - what was I thinking :-)

Now you can click on revisions and diffs again!

(new!) contains.

registers an input file handler for stdin with Tcl and handles Tcl
events until something is available on stdin; it then deletes the
handler and returns from EventHook().

This works with or without GNU readline, and doesn't busy-wait.

It still doesn't work for Mac or Windows :-(

Rationalized the doc strings.

Also simplify the module initialization -- we don't need a __version__
which is set to "$Rev" :-) and we don't need a fatal error when the
initialization fails.

platform's line separator.  \n on Unix, \r\n on DOS, OS/2 and Windows,

Make sure that no tp_as_numbers->nb_<whatever> function is called
without checking for a NULL pointer.  Marc-Andre Lemburg will love it!
(Except that he's just rewritten all this code for a different
approach to coercions ;-( )

argument was initialized to Py_None, but later checked for NULL.
Consistently use Py_None.

func_defaults and func_doc (alias __doc__) may be assigned to.  For
the first two, there's a type restriction to code object and tuple,
respectively.
