## How to reproduce
*(Tested on fresh new installed Virtual Machine)*
### .vimrc

call plug#begin('~/.vim/plugged')
Plug 'junegunn/fzf', { 'do': { -> fzf#install() } }
Plug 'junegunn/fzf.vim'
call plug#end()

1. Install vim, add FZF plugins with vim-plug
2. Go to a directory
3. `mkdir FolderName`
4. Enter vim with the folder in the same directory as the starting point
5. type `:FZF -q FolderName`

## The error
Using the folder "Documents" as an example inside home directory, fzf outputs this:

0/0 (0)
Documents/--expected=ctrl-v,ctrl-x,ctrl-t
