Updated & Fixed: shortcuts in fish for repositories

- order more logical (to me)
- needed some "echo" to prevent overwriting the prompt line

Note: maybe there is a way to remove the prompt at this line and only
draw it after the messages? repaint already does a part of the job.
Fixed: issues with colors in tmux

Apparently tmux's terminfo use 'screen' by default and using the native
terminfo seems incorrect. Hopefully there is a 256color version of
screen terminfo.
