It is needed so that tokenizer.c can use PySys_WriteStderr().

1) I added a command queue which is helpful to me (at least so far) and
   would also allow syntax like 's;s' (step; step) in conjunction with precmd
2) doc_leader allows the derived class to print a message before the help
   output.  Defaults to current practise of a blank line
3) nohelp allows one to override the 'No help on' message.  I need
    'Undefined command: "%s".  Try "help".'
4) Pass line to self.precmd to allow one to do some parsing: change first
   word to lower case, strip out a leading number, whatever.
5) Pass the result of onecmd and the input line to postcmd.  This allows
   one to ponder the stop result before it is effective.
6) emptyline() requires a   if self.lastcmd:  conditional because if the
   first command is null (<cr>), you get an infinite recursion with the
   code as it stands.

that file in fact did not exist or at least was not used.  Change this
so that __file__ is *only* set to the .pyc/.pyo file when it actually
read the code object from it; otherwise __file__ is set to the .py
file.

happen when you use a non-keyword argument after a keyword argument,
and in this case you also get a syntax error.  I fully suspect that
the underflow is caused by the code that stops generating code when it
detects the syntax error, but I can't find the culprit right now.  I
know, I know.)

use it in tokenizer.c.

Metrowerks specific #ifdef.

The MS compiler doesn't call it 'long long', it uses __int64,
so a new #define, LONG_LONG, has been added and all occurrences
of 'long long' are replaced with it.

2-digit years are now converted using rules that are (according to
Fredrik Lundh) recommended by POSIX or X/Open: 0-68 mean 2000-2068,
69-99 mean 1969-1999.

2-digit years are now only accepted if time.accept2dyear is set to a
nonzero integer; if it is zero or not an integer or absent, only year
values >= 1900 are accepted.  Year values 100-1899 and negative year
values are never accepted.

The initial value of time.accept2dyear depends on the environment
variable PYTHONY2K: if PYTHONY2K is set and non-empty,
time.accept2dyear is initialized to 0; if PYTHONY2K is empty or not
set, time.accept2dyear is initialized to 0.

and x is not an instance of C (nor of a class derived of C).

mktime() and such.

This is a patch that Bill Bummgarner did for 1.4 that hasn't made its
way into the distribution yet.  This is important if you want to use
the ObjC module.

shell buffers.

(py-shell): Moved the require of comint to the top level.  Also
use-local-map py-shell-map instead of hacking on the comint-mode-map.
This eliminates breakage of other comint-mode buffers (e.g. shell).

interactions with newer Emacsen, I've rewritten the way all the
process filters work in the *Python* buffer.  We use more of the
comint infrastructure, specifically the default process filter.  This
means that scrolling is now handled by the default comint variables
including comint-scroll-to-bottom-on-output.  Note that this is
somewhat experimental change!

(py-comint-output-filter-function): Moved to here from the obsolete
py-process-filter function, the logic to pop and exec the next queued
file waiting to be executed.

(py-execute-file): Don't bind comint-scroll-to-bottom-on-output to t,
and save the excursion when inserting the "working on" message.  This
lets the standard comint scrolling variables as set by the user,
continue to work.

(python-mode, py-shell, py-describe-mode): Remove description of
py-scroll-process-buffer.  Also in py-shell, make
comint-output-filter-functions buffer-local, and add
py-comint-output-filter-function to this hook (instead of setting the
process filter).

(py-scroll-process-buffer): Deleted this variable.  See comint
variables including comint-scroll-to-bottom-on-output.

(py-execute-region): When exec files are being queued, push the next
temp file on the end of the list.

(py-submit-bug-report): Removed reporting of py-scroll-process-buffer.

As everything is also under CVS this should greatly simplify the work to be done
when a new version of one of the libraries we use is released.

    takes too long. This example relies on the fact that raising an
    exception in a signal handler causes the exception to be re-raised
    when the main line of the program resumes execution.  Is this guaranteed
    in CPython, or is this something that just happens to work by accident?

Also fixed a typo.

objects; this makes the emulation of file objects a bit better, and the
exceptions explain things a bit better.
