Suggested completion should not word wrap

[lilyball]

When fish shows me the suggested completion for what I've already typed, it shouldn't word-wrap this completion. The word wrapping can cause it to flicker between having me type on the first line and having the word I'm typing be wrapped onto the second, based on the current suggested autocomplete. Instead, it should character-wrap the suggested autocomplete (or at least the first word of it) and only word wrap actual typed text.

The best I've been able to do was committed as f8b4c1b.

What I did was made it append an ellipsis for the autosuggestion (and not wrap at all).

Awesome, that should be good enough. Thanks!

This is working well in OS X...not so well in Linux.

Never mind, I was testing on an old version in Linux - it works well there too.
