test will also fail on Linux now.

displays a recognizable section title (there are extra blanks at the
end of it now, due to the nested anchor, but that's fine).

pointers is a signed type.  Changing "allocated" to a signed int makes
undetected overflow more likely, but there was no overflow detection
before either.

top-level node, uselessly chewing up horizontal space, and ensuring that
the only thing the user saw in the TOC upon opening the file was a single
collapsed top-level folder.

HTML (or, at least, proper in its view).  The TOC file is now identical
to what the HTML compiler itself generates, except for whitespace and
a glitch identified below.  The pretty-printing done by prechm.py is
pretty much destroyed for now; if you need it pretty-printed, just make
the Help Compiler save the files (it's got its own idea of pretty-
printing anyway).

Glitch:  The title of Ref Man "2.1.6 Blank lines" shows up as a blank
for now.  This is because the relevant entry in ref/index.html contains
nested anchors, and pychm really has no idea what to do with that.  I
hacked it for now to avoid any error messages or worse insanity, and
filed a bug report against the docs.

methods to squash code duplication.  Simplified several overly complex
chunks of logic.  Built output strings more with string interpolation
instead of infix '+'.  Added comments.  Exploited recent Python features
(chiefly bool and augmented assignment).

Fixes #494762.

Related to SF bug #505315

PyFrame_FastToLocals() and PyFrame_LocalsToFast() had a return if
f_nlocals was 0.  I think this was a holdover from the pre 2.1 days
when regular locals were the only kind of local variables.

The change makes it possible to use a free variable in eval or exec if
it the variable is also used elsewhere in the same block, which is
what the documentation says.

to reference fields via names instead of meaningless little integers.
This turned up one case where the wrong little integer was being used,
in informative progress output.  Fixed that too.

SF bug #522264 reported by Evelyn Mitchell.

The code included a comment about "STAR STAR" which was translated
into the code as the bogus attribute token.STARSTAR.  This name never
caused an attribute error because it was never retrieved.  The code
was based on an old version of the grammar that specified kwargs as
two tokens ('*' '*').  I checked as far back as 2.1 and didn't find
this production.

The fix is simple, because token.DOUBLESTAR is the only token
allowed.  Also update the grammar fragment in com_arglist().

XXX I'll bet lots of other grammar fragments in comments are out of
date, probably in this module and in compile.c.

Will backport to 2.2.

Bug fix candidate for 2.2, not present in 2.1.

pymalloc, apparently. Fixed, but this means all bgen-generated modules will
have to be re-generated.

I hope (and expect) that the pymalloc fixes aren't bugfix candidates, because
if they are this is one too.

Will backport to 2.1 and 2.2.

Close a file before trying to unlink it, and apparently Cygwin needs
writes to an mmap'ed file to get flushed before they're visible.

Bugfix candidate, but I think only for the 2.2 line (it's testing
features that I think were new in 2.2).
