Reduce complexity and fix a regex.t based on observation by rpluem;

 - follow the same logic of '=' for >[=] and <[=], skipping p->type chars
   for the resulting p->pattern

 - introduce pskip logic to greatly simplify logging, track negation '!', '=',
   and new comparators ">/<[=]", backspacing only for the purpose of logging.
   It's trivial to expand this to the -X operators in the future.
