added details of new IMAP4_stream class; emphasised meaning of data part of command results; added proxyauth command description

Already supported dict() and dict(mapping).
Now supports dict(itemsequence) and
Just van Rossum's new syntax for dict(keywordargs).

Also, added related unittests.

The docs already promise dict-like behavior
so no update is needed there.

long but the double is too big to fit in a long.  Prevent that.  This
closes some recent bug or patch on SF, but SF is down now so I can't
say which.

Bugfix candidate.

interrupted.  A try/finally will do nicely.  Maybe other classes need
this too, but since they manipulate more state it's less clear that
that is always the right thing, and I'm in a hurry.

Backport candidate.

prototypes explicitly.

the --disable-unicode build doesn't complain about an
unused variable.

        Previously archive_util.py attempted to spawn an
        external 'zip' program for the zip action, if this fails, an
        attempt to import zipfile.py is made...

        This bites folks who have 'old' or non-conforming zip
        programs on windows platforms.  This change tries the 'zipfile'
        module first, falling back to spawning a zip process if
        the module isn't available.

put more in the critical section than absolutely needed, acquire
the mutex before the "try".

more often than it is.  In response to bug:

[ 641808 ] Portability of Modules/_cursesmodule.c

submitted by Nick Mclaren.

Todo:
- command line parsing
- main program
- modulefinder(-like ;-) support to build standalone apps.

[ 634250 ] SearchDialogBase.py fix for Tk 8.4.1

SearchDialogBase refers to the grid 'col' option
considered ambiguous with Python 2.2.2 and Tk 8.4.1.
The correct name is 'column'.

Make sure we have a UNIX-compatible termios.
Apparently, McMillan Installer made a termios on windows
which caused unix_getpass() to be used instead of win_getpass().

Will backport.

- don't encode/escape elements
- fixed typo in doc string
- provide our own copy function for the Dict class

/usr/bin/python.

Re-order the "porting" section to list items by decreasing significance

the codecs docstrings.
