See <http://bts.grml.org/grml/issue528>.

  - transform [[ -z $PARAM ]] etc. tests to:
    [[ $PARAM -gt 0 ]] and [[ $PARAM -eq 0 ]]
  - fix a problem when /etc/zsh/functions.d
  - do not load zsh/zprof as it might be loaded already
  - *update* the battery status in $RPS1 each time its redrawn.
    only happens if the feature is enabled when sourcing zshrc.
