Long items should not wrap

[mdietz94]

If they wrap, it causes the text to overlap with the text on the next line, and can happen for instance if tab completing directories that contain a hyphen.

@mdietz94 can you provide before and after screenshots? Could you also see if this was reported in any issue before and if so link the PR to an issue?

[mdietz94]

Attached are pictures from before (with wrapping) and after my fix. I could not find any open issues that were related to this problem (though I could create one if you need).

The bottom picture is before and the top picture was after my fix. As you can see post fix you can actually tell what is being completed. Sorry for all the comments I was having trouble uploading the images.

Thanks!
