Idlefork SF Bug 440383 - IDLE goes into beep loop
Fix loop in EditorWindow.newline_and_indent_event() and
in addition fix submission of >>> prompt to PyParse.Parser

Eliminate extra attribute EditorWindow.auto_indent

way to get various alias creation routines as methods of FSSpec or FSRef
objects (which is the logical thing, from a Python POV). Also started on
the code that will contain all the macfs functionality, so macfs can
becode a Python module, to be used mainly for backward compatibility.

Replaced British spelling of 'behaviour' with 'behavior'.
Noted the new optional argument in math.log(x [,base]).

M PyShell.py

* Could not remove last set of saved breakpoints from a file
* Starting with empty edit window, could not load a file
* Multiple adjacent breakpoints were saved as one breakpoint
* Storing breakpoints whenever a file is closed can get them out
  of synch with the saved version of a file.  Only store them when the
  file is saved.
* Add comment on current limitations on file editing in the presence of
  breakpoints.
* Replace get_current_breaks() with update_breakpoints(), add an update to
  PyShellEditorWindow.breakpoints, which is the master breakpoint data
  structure, and which is used to reload the subprocess debugger.
* Revert Debugger.Debugger.load_breakpoints() to use editwin.breakpoints.
  It is easier to debug the debugger if the breakpoint list in IDLE is
  identical to the list in the subprocess debugger and is transferred when
  the subprocess debugger is restarted, because this list can be easily
  queried.
* Cleanup some linespacing and comments in IOBinding.py

Tweaked GetArgv() dialog to look better on OSX.

Sigh: the Jaguar workaround for the prefs file broke saving it on OS9. Temporary workaround is to ignore the exception (it's only about file creator/type anyway).

PyMapping_Check() doesn't guarantee that PyMapping_Size() won't raise
an exception, nor that keys and values are lists.

Also folded some long lines and did a little whitespace normalization.

Probably a 2.2 backport candidate.

(unfortunately: especially the grail demo was hiarious) still missing.

tree. Removed them, anyone really desparate to recover them can get them
from the CVS repository.

that version doesn't need these workarounds.
