Bugfix candidate -- although this is getting harder to backstitch, and the
cases it's protecting against are mondo contrived.

This code is likely to get even hairier to squash core dumps due to
mutating comparisons, and it's hard enough to follow without that.

In particular, the affect on existing list content was not sufficiently
explained.

it in without further ado.

exactly once.  But the test code can't know that, as the number of times
__cmp__ is called depends on internal details of the dict implementation.
This is especially nasty because the __hash__ method returns the address
of the class object, so the hash codes seen by the dict can vary across
runs, causing the dict to use a different probe order across runs.  I
just happened to see this test fail about 1 run in 7 today, but only
under a release build and when passing -O to Python.  So, changed the test
to be predictable across runs.

In the default branch, keep three ifs that are used if level == 0, the
most common case.  Note that first if here is a slight optimization
for the 'O' format.

Note that lots of code was re-indented.

Replace two-step of convertsimple() and convertsimple1() with
convertsimple() and helper converterr(), which is called to format
error messages when convertsimple() fails.  The old code did all the
real work in convertsimple1(), but deferred error message formatting
to conversimple().  The result was paying the price of a second
function call on every call just to format error messages in the
failure cases.

Factor out of the buffer-handling code in convertsimple() and package
it as convertbuffer().

Add two macros to ease readability of Unicode coversions,
UNICODE_DEFAULT_ENCODING() and CONV_UNICODE, an error string.

The convertsimple() routine had awful indentation problems, primarily
because there were two tabs between the case line and the body of the
case statements.  This patch reformats the entire function to have a
single tab between case line and case body, which makes the code
easier to read (and consistent with ceval).  The introduction of
converterr() exacerbated the problem and prompted this fix.

Also, eliminate non-standard whitespace after opening paren and before
closing paren in a few if statements.
