$z matches 1 more \w than ': eg, <code>>B< or >``Es`KI`B<</code>, etc.
Except for those ```S's, this generally results in a slightly shorter (different) line.
Changing the 'p' handling to:<code>
|`i($z) (?{$R++,$q=6})|`p($z) (?{$X=$R;$R=0;$q=7})
. . .
:($15, (chr 120-$X), $bind{$17}, "")[$q-6];
</code>
will let you print (selectively) at the bottom of the loop. (or get ready to do a lot of speed-reading:)
eg,     <code> ++$xx; $q==7 and print "$xx: (", length(), ') ', substr $_,0,80;</code>
