output_difference method access to more information, such as the
indentation of the example, which might be useful.

Mac-specific modules.  Before all modules were compiled but would fail thanks
to a dependence on the code included when Python was built without the compiler
flag.

Closes bug #991962.

NDIFF_DIFF->REPORT_NDIFF.  This establishes the naming convention that
all reporting options should begin with "REPORT_" (since reporting
options are a different class from output comparison options; but they
are both set in optionflags).

- If `want` or `got` is empty, then print "Expected nothing\n" or
  "Got nothing\n" rather than "Expected:\n" or "Got:\n"

* Add comment bars segregating this code from the rest.
* Improve readability of the re pattern with indentation and comments on

* Replace the groupdict() and get() pair with a direct call to group()

exception message, or None if no exception is expected); and moved
exception parsing from DocTestRunner to DocTestParser.  This is
architecturally cleaner, since it moves all parsing work to
DocTestParser; and it should make it easier for code outside
DocTestRunner (notably debugging code) to properly handle expected
exceptions.

a traceback message.  I.e., examples that raise exceptions may no
longer generate pre-exception output.  This restores the behavior of
doctest in python 2.3.  The ability to check pre-exception output is
being removed because it makes the documentation simpler; and because
there are very few use cases for it.

Allows the lineno fixup code to remain simple and not have to deal with
multibyte codings.

* Add an assertion to that effect.
* Remove the XXX comment on the subject.

This patch includes test cases and documentation updates, as well as NEWS file
updates.

This patch also updates the sre modules so that they don't import the string
module, breaking direct circular imports.

but I find the default setting of allow_interspersed_args very weird.

* Perform the code length check earlier.
* Eliminate the extra PyMem_Free() upon hitting an EXTENDED_ARG.
* Assert that the NOP count used in jump retargeting matches the NOPs
  eliminated in the final step.
* Add an XXX note to indicate that more work is being to done to
  handle linenotab with intervals > 255.

* Make a pass to eliminate NOPs.  Produce code that is more readable,
  more compact, and a tiny bit faster.  Makes the peepholer more flexible
  in the scope of allowable transformations.

* With Guido's okay, bumped up the magic number so that this patch gets
  widely exercised before the alpha goes out.

Now joining string subtypes will always return a string.
Formerly, if there were only one item, it was returned unchanged.
