Perform tilde expansion when completing flake fragments Allows completing `nix build ~/flake#<Tab>`. We can implement expansion for `~user` later if needed. Not using wordexp(3) since that expands way too much. 2022-02-19 13:26:34 +00:00			`done < <(NIX_GET_COMPLETIONS=$cword "${words[@]}" 2>/dev/null)`
