Problem passing "--icons --tree" to `fifc_exa_opts`

[macintacos]

Describe the bug

I'm setting the fifc_exa_opts option like so:

set -U fifc_exa_opts "--icons --tree"

And when I hit "tab" after typing cd, I see an error in the preview that says:

exa: Unknown argument --icons --tree

This command works fine if executed directly, and I'm running the latest version of exa available.

To Reproduce

Set the option like I did above

Expected behavior

The preview would look like the output of exa --icons --tree.

System (please complete the following information):

• fish version - 3.6.1
• Distribution cat /etc/os-release - macOS 13.4.1

Hi @macintacos!

This should be solved by setting options as list instead of string:

set -U fifc_exa_opts --icons --tree

Will mention it in the readme, thanks for the report!
