  // the t-function's variable interpolation.  This finds all sets of word
  // characters (A-Z, a-z, - or _) that begin with either !, @, or %, that do not
  // fall between angle brackets (which would indicate being on the inside
  // of an HTML tag).  It also protects everything inside square brackets
