semantics to include subtypes. Most concrete object APIs then had
a Py<type>_CheckExact() macro added to test for an object's type
not including subtypes.
The PyDict_CheckExact() macro wasn't created at that time, so I've added
it for API completeness/symmetry - even though nobody has complained
about its absence in the time since 2.2 was released.
Not a backport candidate.

PyList_CheckExact() was added at 2.2 but never documented.

Duncan Booth investigated, and discovered that an "optimisation" was
in fact a pessimisation for small numbers of elements in a source list,
compared to not having the optimisation, although with large numbers
of elements in the source list the optimisation was quite beneficial.
He posted his change to comp.lang.python (but not to SF).
Further research has confirmed his assessment that the optimisation only
becomes a net win when the source list has more than 100 elements.
I also found that the optimisation could apply to tuples as well,
but the gains only arrive with source tuples larger than about 320
elements and are nowhere near as significant as the gains with lists,
(~95% gain @ 10000 elements for lists, ~20% gain @ 10000 elements for
tuples) so I haven't proceeded with this.
The code as it was applied the optimisation to list subclasses as
well, and this also appears to be a net loss for all reasonable sized
sources (~80-100% for up to 100 elements, ~20% for more than 500
elements; I tested up to 10000 elements).
Duncan also suggested special casing empty lists, which I've extended
to all empty sequences.
On the basis that list_fill() is only ever called with a list for the
result argument, testing for the source being the destination has
now happens before testing source types.
bit by checking the value of UCHAR_MAX in Include/Python.h. There was a
check in Objects/stringobject.c. Remove that. (Note that we don't define
UCHAR_MAX if it's not defined as the old test did.)
* in py-checker-run, fall back to read-string if read-shell-command
(XEmacs-specific) is not available.
* highlight variables would mask builtins as if they were keywords.
The chief benefit of this change is that requests will now use
HTTP/1.1 instead of HTTP/1.0. Bump the module version number as part
of the change.
There are two possible incompatibilities that we'll need to watch out
for when we get to an alpha release. We may get a different class of
exceptions out of httplib, and the do_open() method changed its
signature. The latter is only important if anyone actually subclasses
AbstractHTTPHandler.
