Ctrl-c not working correctly in python about athame HOT 4 CLOSED

Tab should be fixed now in python and ipython. Control C is still broken.

from athame.

Fixed in 1.0 branch.

Tab is also broken in Python shell, but I'm still looking into why. I
haven't used iPython; I'll have to see what is wrong with Ctrl-c. Thanks
for letting me know!

Without athame, the behaviour of these keys is as following:

• Tab: inserts a tab
• Ctrl-c: cancels the current line edit and KeyboardInterrupt is
  printed

With athame in insert mode:

• Tab: in the beginning of the line it inserts a tab correctly, but
  seem to think that a new line is edited- the -- INSERT -- is gone
  until I type anything. When I start typing anything after the tab it goes
  into insert mode again but starts from the beginning of the line, ignoring
  the tab (like cc was used in vim).
• Ctrl-c: if this is the first thing I do on a new line, before the --
  INSERT -- indicator appears, it works as expected. However after the
  indicator appears it seems to ignore the Ctrl-c untill I press return, at
  which point I get the KeyboardInterrupt message.

Using IPython 4.0.1.

Thanks!

Changing to just cover python because ipython now uses prompt_toolkit instead of readline (covered in #35).

The reason this is non-trivial to fix is that:

1. control C sends a SIGINT instead of a keypress. This signal is handled by python.
2. python doesn't tell readline about signals like bash does, so athame can't just use readline code to tell if it got the signal.
3. python doesn't give control back to readline until it gets another keypress, so if we give control back to it after every key like normal readline, we break CursorHold, imaps timing out, anything async, etc among other problems.
