The supported parameters are:
- `--prevent-extra` *(experimental)*: limits the user to select one of the suggestions;
- `--column <number>`: extracts a single column from the selected result;
- `--delimiter <regex>`: delimits columns + forwarded option to `fzf`;
- `--multi`: forwarded option to `fzf`;
- `--header-lines <number>`: forwarded option to `fzf`;
In addition, it's possible to forward the following parameters to `fzf`:
- `--header-lines <number>`;
- `--delimiter <regex>`;
- `--query <text>`;
- `--filter <text>`;
- `--header <text>`;
- `--preview <code>`;
