Can you submit this change as a separate patch, as it is unrelated to
the python-prompt-toolkit update?

I think you need to re-add these inputs in 'python-prompt-toolkit-2'.
'python2-prompt-toolkit' should probably inherit from
'python-prompt-toolkit-2' too, given that the dependency on Six is
removed in version 3.

Finally 'python-prompt-toolkit-1' (!!!) also needs to inherit from
'python-prompt-toolkit-2' so that the inputs don't change, unless
version 1 can be removed entirely.

Quite the cabal!
