Hacking on zsh-syntax-highlighting itself

This document includes information for people working on z-sy-h itself: on the
core driver (zsh-syntax-highlighting.zsh), on the highlighters in the
distribution, and on the test suite. It does not target third-party
highlighter authors (although they may find it an interesting read).

The 'main' highlighter

The following function pz is useful when working on the main highlighting:

pq() {
  (( $#argv )) || return 0
  print -r -l -- ${(qqqq)argv}
}
pz() {
  local arg
  for arg; do
    pq ${(z)arg}
  done
}

It prints, for each argument, its token breakdown, similar to how the main
loop of the main highlighter sees it.
