I have an alias nsz which runs a nix-shell with zsh.
But the $SHELL is still bash.
I now change the SHELL variable in order to use my expected shell in all
circumstances.
I also ensure neovim will use zsh for commands as some of my auto
commands expect this shell for expansion of **.
This allows to easily switch to tmux copy mode and navigate between
paragraphs / prompts and results. As long as the output doesn't have
additional blank lines.
This reverts commit b929c17ace.
As I don't like the small interrupt.
Also I don't like to have the same setup in this case. I prefer to keep
focus on the input and therefore seeing suggestions right there.
