I can not open a file that contains LF in the name

- [ ] I have read through https://github.com/junegunn/fzf.vim/blob/master/README.md

- [ ] I have read through the manual page of fzf (`man fzf`)
- [ ] I have searched through the existing issues

When I create a file that contains LF:

```
echo aaa > "$(printf 'aa\nbb')"
```

I can not use FZF to open it.

One of the workaround that I've found is to use `:edit **/*` instead of FZF

Reproduce the issue with the provided shell command, then compare FZF's handling of the generated filename with Vim's :edit **/* workaround. Trace the file-opening path used by the plugin and verify that a filename containing LF can be selected and opened without changing the existing workaround behavior.
