[fish] Yank commandline in fzf-history-widget

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.

[bash-completion] Fix #668

Handle uppercase letters in program names. This also deals with `-` and
`.`, both of which are quite common in program names, e.g., `xdg-open`
and `foo.sh`.
