Fix unintuitive result where `*fzf*/install` is ranked higher than
`fzf/src/fzf/*fzf*-linux_386` on --tiebreak=end.

This is a breaking change, but I believe it makes much more sense. It is
almost impossible to predict which entries will be filtered out due to
a fuzzy inverse term. You can still perform inverse-fuzzy-match by
prepending `!'` to the term.

| Token    | Match type                 | Description                       |
| -------- | -------------------------- | --------------------------------- |
| `sbtrkt` | fuzzy-match                | Items that match `sbtrkt`         |
| `^music` | prefix-exact-match         | Items that start with `music`     |
| `.mp3$`  | suffix-exact-match         | Items that end with `.mp3`        |
| `'wild`  | exact-match (quoted)       | Items that include `wild`         |
| `!fire`  | inverse-exact-match        | Items that do not include `fire`  |
| `!.mp3$` | inverse-suffix-exact-match | Items that do not end with `.mp3` |

It was possible that a few lines at the bottom may not be visible if
there are lines above that span multiple lines.

You can use your mouse or binadble preview-up and preview-down actions
to scroll the content of the preview window.

Use hard-coded limit to keep it simple. An alternative is to dynamically
calculate the width of the visible area and use it as the limit, but it
can cause unwanted truncation of the query on screen resize/split.
