Added special case to unicode(): when being passed a
Unicode object as first argument, return the object as-is.
Raises an exception when given a Unicode object *and* an
encoding name.
Fix description; lowercase and uppercase are strings, not
functions! Noted by Randall Hopper <aa8vb@yahoo.com>.

default list of files from () to None, and explicitly test for None
before defaulting to sys.argv[1:]. This means that if you pass in an
explicit empty list, it will read stdin instead of defaulting to
sys.argv[1:]. This fixes a buglet in the test script (when called
with options but without files, it chokes when it tries to interpret
the options as files).
Lawrence adds: "I suspect that this is a safe change, because I can't
imagine someone actively passing in an empty list when they want
sys.argv used."
I agree.
comparing code objects. This give sless surprising results in
-Optimized code. It also sorts code objects by name, now.
[I changed the patch to hash() slightly to touch fewer lines.]
Instead of assuming that the number process ids of the threads is the
same as the process id of the controlling process, use a copy of the
dictionary and check for changes in the process ids of the threads
from the thread's process ids in the parent process. This makes the
test make more sense on systems which assign a new pid to each thread
(i.e., Linux).
This doesn't fix the other problems evident with this test on Linux.
* '...%s...' % u"abc" now coerces to Unicode just like
string methods. Care is taken not to reevaluate already formatted
arguments -- only the first Unicode object appearing in the
argument mapping is looked up twice. Added test cases for
this to test_unicode.py.
* New exported API PyUnicode_Resize()
* The experimental Keep-Alive optimization was turned back
on after some tweaks to the implementation. It should now
work without causing core dumps... this has yet to tested
though (switching it off is easy: see the unicodeobject.c
file for details).
* Fixed a memory leak in the Unicode freelist cleanup code.
* Added tests to correctly process the return code from
_PyUnicode_Resize().
* Fixed a bug in the 'ignore' error handling routines
of some builtin codecs. Added test cases for these to
test_unicode.py.
* string_contains now calls PyUnicode_Contains() only when the other
operand is a Unicode string (not whenever it's not a string).
* New format style '%r' inserts repr(arg) instead of str(arg).
* '...%s...' % u"abc" now coerces to Unicode just like
string methods. Care is taken not to reevaluate already formatted
arguments -- only the first Unicode object appearing in the
argument mapping is looked up twice. Added test cases for
this to test_unicode.py.
In line with a similar checkin to object.c a while ago, this patch
gives a more descriptive error message for an attribute error on a
class instance. The message now looks like:
AttributeError: 'Descriptor' instance has no attribute 'GetReturnType'
