returns ESRCH for a zombie process, which is not POSIX-compliant.

Now pindent.py works with a "with" statement.  pindent.py no longer produces
improper indentation.  pindent.py now works with continued lines broken after
"class" or "def" keywords and with continuations at the start of line.  Added
regression tests for pindent.py.  Modernized pindent.py.

#13899: \A, \Z, and \B now correctly match the A, Z, and B literals when used inside character classes (e.g. [A]).  Patch by Matthew Barnett.

With '%', non-ascii worked because the '%' automatically got promoted to
unicode.  With format that doesn't happen, which led to encoding errors.  This
fix goes back to using %, and adds a test to make sure non-ascii string values
work in iterdump.

Although there is not a regression in Python2, we make the same update here to
keep the code bases in sync.

(The fix for issue 9750 introduced a regression in Python 3 by sorting the row
objects returned by fetchall.  But if a row_factory such as sqlite3.Row is
used, the rows may not be sortable (in Python3), which leads to an exception.
The sorting is still a nice idea, so the patch moves the sort into the sql.)

Fix and test by Peter Otten.

_Qdoffs when compiling with an SDK of 10.7 or later.  The OS X APIs they
wrap have long been deprecated and have now been removed with 10.7.
These modules were already empty for 64-bit builds and have been removed
in Python 3.  (Original patch by Ronald Oussoren.)
