• be friendlier to AT&T ksh: use only signed (standard) integers 

‣ now, a “ksh93” just requires ‘function precmd { :; }; set -o emacs’
    afterwards to get rid of the annoying error messages
  ‣ I could lose that with the following idiom:
    - PS1='$(precmd)…
    + PS1='$(typeset -i e=$?; typeset -f precmd >&- && { (return $e); precmd })…
    but it didn’t seem worthwhile to me
• remove explicit licence blah, normal ./copyright applies
