Perl chomp only removes -all- traliing newlines when in paragraph mode.
Paragraph mode is when $/ is set to "".  The default mode is not paragraph
mode, so chomp removes only one (1) newline.

=== code
$s = "now\n\n\n";
print "length($s) = ".length($s)."\n";
chomp($s);
print "length($s) = ".length($s)."\n";

=== output
length(now


) = 6
length(now

) = 5
