Checkin updated version of patch #103933 .  As Thomas says, fixes the bugs #131064, #129584, #127722. See the discussion in bug #131064

Move sample sessions to the left margin of the file for consistency;
formatting can adjust the margin if needed.

This closes SF bug #133213.

and the test for errors, so that an error in the default compare
doesn't go undetected.  This fixes SF Bug #132933 (submitted by
effbot) -- list.sort doesn't detect comparision errors.

    (Fred, I'll leave the doc changes to you, because I don't know if you
     want to delete libsoundex.tex or leave it in.
     Someone else will have to tweak PC/os2vacpp/{config.c,makefile} and
     PCbuild/pythoncore.dsp, both of which refer to soundex.c)

The bug report title isn't correct, but was on the right track.
Rev 2.13 applied a patch intended to improve asinh and acosh, but the
author mistakenly replaced the body of asin with their new code for asinh.
See bug report for all the gory details.
This patch: (a) puts the "new" (as of 2.13) asinh code into the asinh
function; and, (b) repairs asin via what Abramowitz & Stegun say it should
be (which is probably the same as what 2.12 did for asin, although I got
tired of matching parentheses before being 100% sure of that -- and I don't
care!  The source of the old code is a mystery, and I *know* why I picked
the new code.).

  * fixes the zlib decompress sync flush bug as reported in bug #124981
  * avoids repeat calls to (in|de)flateEnd when destroying (de)compression
    objects
  * raises exception when allocating unused_data fails
  * fixes memory leak when allocating unused_data fails
  * raises exception when allocating decompress data fails
  * removes vestigial code from decompress flush now that decompression
    returns all available data
  * tidies code so object compress/decompress/flush routines are consistent

 NamedNodeMap.setNamedItem().  Martin, should I sync the PyXML tree, too,
 or do you want to do it?  (I don't know if you're wrapping the 0.6.4
 release right now.)

On OSX passing NULL to NewUniversalFilterProc() does not return NULL but a crashing UPP. This made ModalDialog (and, hence EditPythonPrefs and EasyDialogs and many others) crash. Fixed.

cookies that contain '=' as part of the value. This patch modifies
Cookie.py to allow '=' as a legal character, and to make the key
search nongreedy so it stops at the first '='.

save the __builtin__ module in a static variable.  But this doesn't
work across Py_Finalise()/Py_Initialize()!  It also doesn't work when
using multiple interpreter states created with PyInterpreterState_New().

So I'm ripping out this small optimization.

This was probably broken since PyImport_Import() was introduced in
1997!  We really need a better test suite for multiple interpreter
states and repeatedly initializing.

This fixes the problems Barry reported in Demo/embed/loop.c.

Added `realclean' target.
