Including spaces for autocomplete

[kaustubh-nair]

@rr- We have this need in zulip-terminal of taking spaces into account while using autocomplete (for example, autocompleting full names of users)
Would it be possible to achieve this with the current features of urwid_readline? If not, is this something that can be added to readline?

It does not support it afaik but it definitely can. However, since my capacity to work on open source these days is very low, I'd appreciate a pull request.

Looking back at this, I'd expect #16 fixed this?
