Fixes #661762, bugfix candidate.

FSSpec.SetDates() and GetDates(). Closes #662836.

(Someone please review what I wrote for accuracy.)

* Add doctest for example in the library reference manual

Note, that list.sort() is undefined for lists of sets.
Add the ... prompt to the example so it runs in doctest.

                              and unicode

Patch by Christopher Blunck.

Ensure that the 'size' arg is correctly passed to the encoding reader to
prevent buffer overflows.

Configuration implementation.

- Change default: IDLE now starts with Python Shell.

- Removed the File Path from the Additional Help Sources scrolled list.

- Add capability to access Additional Help Sources on the web if the
  Help File Path begins with //http or www.  (Otherwise local path is
  validated, as before.)

- Additional Help Sources were not being posted on the Help menu in the
  order entered.  Implement sorting the list by [HelpFiles] 'option'
  number.

- Add Browse button to New Help Source dialog.  Arrange to start in
  Python/Doc if platform is Windows, otherwise start in current directory.

- Put the Additional Help Sources directly on the Help menu instead of in
  an Extra Help cascade menu.  Rearrange the Help menu so the Additional
  Help Sources come last.  Update help.txt appropriately.

- Fix Tk root pop-ups in configSectionNameDialog.py  and configDialog.py

is not supported on sets.  (Unfortunately, sorting a list of sets may
still return random results because it uses < exclusively, but for
sets that inly implements a partial ordering.  Oh well.)

The two are semantically equivalent, but the first triggered a compiler
warning about an unused variable.  Note, the preceding steps had already
accessed and decreffed the variable so the reference counts were fine.

inspect.getsource would crash with one line definitions like:
   def f(x): return x
or
   f = lambda x: x

managed to delete the @test file it intended to delete.  Also, I don't
see a reason to create a 4MB file in the new test, so cut it back to 16K.

This was introduced in 1998 in rev. 1.13, where I imported extensive
patches that, I am sad to say, I didn't review as carefully as I
should have.

do_quit() -- but print a blank line first.

Fix infinite recursion which occurred when printing an object
whose __str__() returned self.

Will backport

   C API section by mistake

Mention deprecation of string exceptions

'%s' % u'x'  return a unicode object.

The interpreter doesn't crash, but it does call exit() in libncurses.
Add a note to this effect.

Will backport

HASTZINFO() macro.

Add the optional gain parameter and pass it to Tk.

When a module doesn't have a __path__ attribute, trigger a dialog box
rather than dumping a traceback to the console.

Synch to Python IDLE.

Closing an mmap'ed file (calling munmap) twice on Solaris caused a core dump.

M configHelpSourceEdit.py

1. Attach configHelpSourceEdit error dialogs to parent to avoid Tk root
   pop-ups.
2. Make configHelpSourceEdit OK button the default and bind <Return>.
3. Reformat configHelpSourceEdit.
4. ConfigDialog.SaveAllChangedConfig() had a bug which caused additional
   help sources to be deleted when other config items were changed.
4. Uniform capitalization in configDialog.
5. Update configDialog doc string.
