Keybinding "g l" (goto line end) is broken

Function (sed) gives the error `sed: 1: "1!b;/^$/q;q5": undefined label ';/^$/q;q5'`

``` fish
function __fish_helix_goto_line_end
    # check if we are on an empty line first
    commandline | sed -n (commandline -L)'!b;/^$/q;q5' && return
    commandline -f end-of-line backward-char
end
```

(EDIT: Closed PR, because I've discovered more issues with other functions)
