Hi,

I am having an issue with fzf.vim in neovim. For some reason, what looks like the value of an old `FZF_DEFAULT_COMMAND` variable is being printed out as part of the file listing.

I say old value as my default command in my `.vimrc` currently looks like this:

```
"""
" FZF
"""
let $FZF_DEFAULT_COMMAND='rg --files --smart-case'
nnoremap :Files
```

and my zshrc currently looks like this

```
# Set fzf command to use rg
export FZF_DEFAULT_COMMAND='rg --files --no-ignore-vcs --hidden'
```

I have tried uninstalling and reinstalling the plugin and FZF from my system and restarting the computer and it doesn't seem to make a difference. The problem persists across NeoVim, Vim and Vim with a minimal config (as suggested above).

It is also worth noting that this doesn't happen when you run fzf outside of vim.

Any idea what might be happening?

Thanks,

Tom
