v0.56.0

- Added `--gap[=N]` option to display empty lines between items.
    - This can be useful to visually separate adjacent multi-line items.
      ```sh
      # All bash functions, highlighted
      declare -f | perl -0777 -pe 's/^}\n/}\0/gm' |
        bat --plain --language bash --color always |
        fzf --read0 --ansi --reverse --multi --highlight-line --gap
      ```

    - Or just to make the list easier to read. For single-line items, you probably want to set `--color gutter:-1` as well to hide the gutter.
      ```sh
      fzf --info inline-right --gap --color gutter:-1
      ```

- Added `noinfo` option to `--preview-window` to hide the scroll indicator in the preview window
