the prompt may not be updated without repaint

Thanks for the PR.

Correct me if I'm wrong (I don't have much experience with the fish shell), but I'm not sure if this is needed though? Repainting the prompt would make sense if triggered from a keybinding, but that is already mentioned in the comment above:

# You may also like to assign a key (Ctrl-O) to this command:
#
#     bind \co 'set old_tty (stty -g); stty sane; lfcd; stty $old_tty; commandline -f repaint'
#
