As roboticus pointed out, this: 
         $delaylist{ $_ } = $msg;

[download]
essentially says one message per nick. You could replace it with something like 
         $delaylist{ $_ } .= $msg;

[download]
which adds to the (still one) message (perhaps should add a linefeed or some such), or 
         push @{$delaylist{ $_ }}, $msg;

[download]
which says multiple messages per nick - housekeeping left as an exercise for the reader ;-)

In the latter case, you might want to change the semantics of delay-remove to remove

to that nick.

(TL;DR essentially the same as this)
