The first line of Python script could be executed twice when the source
encoding was specified on the second line. Now the source encoding
declaration on the second line isn't effective if the first line contains
anything except a comment. 'python -x' works now again with files with the
source encoding declarations, and can be used to make Python batch files on
Windows.

occcurs; tweaked the set of exported symbols; renamed Empty/Full to
QueueEmpty/QueueFull; "with (yield from lock)" now uses a separate context
manager; readexactly() raises if not enough data was read; PTY support
tweaks.

ExitStack.__exit__ could create a self-referential loop if an exception
raised by a cleanup operation already had its context set correctly (for
example, by the @contextmanager decorator). The infinite loop this caused is
now avoided by checking if the expected context is already set before trying
to fix it.
