Currently, test_pty hangs on AIX & HPUX if run after test_openpty.

to 'properly configure the slave terminal'

See SF patch # 656590 for the details.

imports e.g. test_support must do so using an absolute package name
such as "import test.test_support" or "from test import test_support".

This also updates the README in Lib/test, and gets rid of the
duplicate data dirctory in Lib/test/data (replaced by
Lib/email/test/data).

Now Tim and Jack can have at it. :)

time use .replace() to change all \r\n into \n, not just the last one.

mostly changes of / operators into //.  Once or twice I did more or
less than recommended.

linefeeds into carriagereturn-linefeeds (which is apparently what IRIX
does.) Also add some comments, an extra test and reorganize it a bit.

(This one was trivial -- no actual string. references in it!)

'verify' iff it's used by a test module...

and replaces them with a new API verify(). As a result the regression
suite will also perform its tests in optimization mode.

apparently not considered a terminal, and so isatty(3) returns false. So we
skip the test for ttyness of the master side and just check the slave side,
which should really be a terminal.

to signify a test that should be marked as 'skipped' rather than 'failed'.
Also 'document' it, in README.

comments, docstrings or error messages. I fixed two minor things in
test_winreg.py ("didn't" -> "Didn't" and "Didnt" -> "Didn't").

There is a minor style issue involved: Guido seems to have preferred English
grammar (behaviour, honour) in a couple places. This patch changes that to
American, which is the more prominent style in the source. I prefer English
myself, so if English is preferred, I'd be happy to supply a patch myself ;)

Test case for the pty module.
