6    written it more tidily in the first place. Will I ever learn? It has grown and
7    been extended and consequently is now rather, er, *very* untidy in places.

586    /* Input lines are read into buffer, but both patterns and data lines can be
587    continued over multiple input lines. In addition, if the buffer fills up, we
588    want to automatically expand it so as to be able to handle extremely large
589    lines that are needed for certain stress tests. When the input buffer is
590    expanded, the other two buffers must also be expanded likewise, and the
591    contents of pbuffer, which are a copy of the input for callouts, must be
592    preserved (for when expansion happens for a data line). This is not the most
593    optimal way of handling this, but hey, this is just a test program!
