Update fresh prompt

Browse Source 
* When a command fails, don't print the error code at the end of the
  first line but directly after the git stats.
* Remove `cr` from `prompt_opts` since there is no longer a new line in
  `PS1`, combined with above, this result in no new lines being inserted
  when the terminal becomes narrower e.g. a horizontal tmux split.
* Remove `fresh_visible_length` function and instead use the length of
  string variables e.g. `${#userhost}`.
