For sometime I forgot I wrote a class and wrapped it in an existential
just because when I was writing the prompt I was thinking about
expanding the API at a later time in a safe manner... that time has
come...;)

So, now the prompt can complete just the last word of the command
line, or the whole line - which makes it possible to have a theme
selector displaying all the information we want to display, or a
gotoWindow without having to escape everything.

The first is the default behavior and can be tuned, so now it is
possible to have the completions displayed without escaping the space
(or other special character), and have them escaped in the command
line, which was one of the requested features.

The first one (the trailing slash) is not so easy, and this is the
solution I've pushed: if there is just one completion and that
completion is a directory, a trailing slash will be added.

I don't know if it is the right approach, but it is definitely the
simplest one I could think about (and I don't think I'm not going to
think about it twice... so patches are welcome...;).

Please let me know your thoughts.
