[Patch #1068277] Clarify that os.path.exists() can return False depending on permissions.  Fred approved committing this patch in December 2004!

These problems may mask more important, real problems.

One or both methods are known to fail on: Solaris, OpenBSD, Debian, Ubuntu.
They pass on Windows and some Linux boxes.

[Patch #1490989 from Skip Montanaro]  Mention debugging builds in the API documentation.  I've changed Skip's patch to point to Misc/SpecialBuilds and fiddled with the markup a bit.

We want to encourage users to write open() when opening a file, but
open() was described with a single paragraph and
'file' had lots of explanation of the mode and bufsize arguments.

I've shrunk the description of 'file' to cross-reference to the 'File
objects' section, and to open() for an explanation of the arguments.

open() now has all the paragraphs about the mode string.  The bufsize
argument was moved up so that it isn't buried at the end; now there's
1 paragraph on mode, 1 on bufsize, and then 3 more on mode.  Various
other edits and rearrangements were made in the process.

It's probably best to read the final text and not to try to make sense
of the diffs.

  41667, 41668 - initial switch to xmlcore
  47044        - mention of xmlcore in What's New
  50687        - mention of xmlcore in the library reference

re-apply xmlcore changes to xml:
  41674        - line ending changes (re-applied manually), directory props
  41677        - add cElementTree wrapper
  41678        - PSF licensing for etree
  41812        - whitespace normalization
  42724        - fix svn:eol-style settings
  43681, 43682 - remove Python version-compatibility cruft from minidom
  46773        - fix encoding of \r\n\t in attr values in saxutils
  47269        - added XMLParser alias for cElementTree compatibility

additional tests were added in Lib/test/test_sax.py that failed with
the xmlcore changes; these relate to SF bugs #1511497, #1513611

The constructor docs referred the reader to the add_data() method's docs,
but they weren't very helpful.  I've simply copied an earlier explanation
of 'data' that's more useful.

[Bug #1414697] Change docstring of set/frozenset types to specify that the contents are unique.  Raymond, please feel free to edit or revert.

test_compiler now passes again.

docstrings correctly as it did in Python 2.4.

Regenerated Modules/_ctypes/libffi/configure with autoconf 2.59.

with PEP 302.  This was fixed by adding an ``imp.NullImporter`` type that is
used in ``sys.path_importer_cache`` to cache non-directory paths and avoid
excessive filesystem operations during imports.

Cosmetic changes to the code so that the #ifdef _UNICODE block
doesn't mess emacs code formatting.
