Oops, OutputFile was only in Windows readline, fixed.

provide single readline config place through rlineimpl

Try to import pyreadline on win32

ipsystem() -> _ip.system()

-Expose IPApi is _ip in user namespace. -Replace ipmagic with _ip.magic for all interactive execution; therefore, there should be no user_ns['ipmagic'] references in IPython core anymore. - "_ip.options().autoedit_syntax = 2" -> no prompting, just edit

Changed doc on how to enable a hook

GetoptErrors when invoking magics etc. with wrong args are now more helpful.

/f 1 2 -> f(1,2), not f(1 2). I.e. autoparen fixes

Do not change sys.argv to ['-c'] on "-c cmd" command line option.
