For smaller datasets, it is not always true the increasing the compression
level always results in better compression. Removed the test which made
this invalid assumption.

* Convert three test modules to unittest format.
* Expanded coverage in test_structseq.py.
* Raymond added a new test in test_sets.py
When the indents were set to longer than the width and long word breaking
was enabled, an infinite loop would result because the inner loop did not
assure that at least one character was stripped off on every pass.
platforms (e.g., Cygwin) that are "particular" about open files, this will
cause other regression tests that use the same temp file to fail:
$ ./python.exe -E -tt Lib/test/regrtest.py -l
test_largefile test_mmap test_mutants
test_largefile
test test_largefile failed -- got -1794967295L, but expected 2500000001L
test_mmap
test test_mmap crashed -- exceptions.IOError: [Errno 13] Permission denied: '@test'
test_mutants
test test_mutants crashed -- exceptions.IOError: [Errno 13] Permission denied: '@test'
This patch solves the problem by adding missing "try/finally" blocks. Note
that the "large" size of this patch is due to many white space changes --
otherwise, the patch is small.
I tested this patch under Red Hat Linux 8.0 too.
test_rfc2231_no_language_or_charset_in_boundary(),
test_rfc2231_no_language_or_charset_in_charset(): New tests for proper
decoding of some RFC 2231 headers.

get_filename(), get_boundary(), get_content_charset(): Make sure these
handle RFC 2231 headers without a CHARSET field.

* Relaxed the argument restrictions for non-operator methods. They now
allow any iterable instead of requiring a set. This makes the module
a little easier to use and paves the way for an efficient C
implementation which can take better advantage of iterable arguments
while screening out immutables.
* Deprecated Set.update() because it now duplicates Set.union_update()
* Adapted the tests and docs to include the above changes.
* Added more test coverage including testing identities and checking
to make sure non-restartable generators work as arguments.
Will backport to Py2.3.1 so that the interface remains consistent
across versions. The deprecation of update() will be changed to
a FutureWarning.
