[Inline Tab] use shortest match when giving suggestions

[doubledgedboard]

Just like #71, in addition to giving suggestions for substrings, inline tab also gives suggestions for longer completion results first instead of the shortest result, which makes no sense

example, I type Sadge and hit Tab, I get a suggestion of smoketvSadge and if I press tab again then I get a suggestion of Sadge

Not only should it probably prefer something that starts with the input text over a substring, but it should be preferring the shortest match.
