Support fish shell

I’m a fish shell user, and when I invoke, for instance, FzfPreviewProjectFiles I get:

~      ╭──────────────────────────────────────────────────────────────────────────────╮        
~      │ ProjectFiles>                         ┌────────────────────────────────────┐ │

nvim is set up to use good old bash for shell: :echo &shell returns /usr/bin/env bash.

Is there something I’m missing or that I can do?

I was able to fix this by adding the following to my config:

" Since fish shell is the system default, nvim has all kinds of issues
" executing system() calls. Setting `shell` fixes them. fzf-preview still
" seems to use fish though, which setting $SHELL fixes.
set shell=/bin/zsh
let $SHELL = "/bin/zsh"

@yuki-ycino ; even with set shell=bash; i see things like:

fish: Unsupported use of ‘&&’. In fish, please use ‘COMMAND; and COMMAND’.
