Thank you, AM.anomylous. All the words were there in perlvar, but I couldn't put it together without your well-contrived example. It was certainly a teachable moment for me, and I'd like to be able to show it precisely, so I worked up a bash script for the output and layout with monastery-conforming tags. The first script is 1.irs.pl and sets the irs (not the taxers) to the null string. Output, then source listing:

[[line 1 
line 2 





line 8 
line 9 




line 14 



]] 
block 1 <<line 1 
line 2 

>>block 2 <<line 8 
line 9 

>>block 3 <<line 14 

>>#!/usr/bin/perl -w
use strict;

my $data = qq{line 1 \n}
          . qq{line 2 \n}
          . qq{\n}
          . qq{\n}
          . qq{\n}
          . qq{\n}
          . qq{\n}
          . qq{line 8 \n}
          . qq{line 9 \n}
          . qq{\n}
          . qq{\n}
          . qq{\n}
          . qq{\n}
          . qq{line 14 \n}
          . qq{\n}
          . qq{\n}
          . qq{\n}
          ;
 print qq{[[$data]] \n};
 ;;
 open my $dfh, '<', \$data or die $!;
 ;;
 local $/ = '';

 my $counter = 0;
 while (<$dfh>) {
   ++$counter;
   print qq{block $counter <<$_>>};
   }
__END__

2.irs.pl sets the irs to /n/n. Output, then source:

[[line 1 
line 2 





line 8 
line 9 




line 14 



]] 
block 1 <<line 1 
line 2 

>>block 2 <<

>>block 3 <<

>>block 4 <<line 8 
line 9 

>>block 5 <<

>>block 6 <<
line 14 

>>block 7 <<

>>#!/usr/bin/perl -w
use strict;

my $data = qq{line 1 \n}
          . qq{line 2 \n}
          . qq{\n}
          . qq{\n}
          . qq{\n}
          . qq{\n}
          . qq{\n}
          . qq{line 8 \n}
          . qq{line 9 \n}
          . qq{\n}
          . qq{\n}
          . qq{\n}
          . qq{\n}
          . qq{line 14 \n}
          . qq{\n}
          . qq{\n}
          . qq{\n}
          ;
 print qq{[[$data]] \n};
 ;;
 open my $dfh, '<', \$data or die $!;
 ;;
 local $/ = "\n\n";
 my $counter = 0;
 while (<$dfh>) {
   ++$counter;
   print qq{block $counter <<$_>>};
   }

I agree, local $/ = ''; sets what you might call "indulgent" or "greedy" paragraph mode.
