Here's another trick I've used occasionally that involves chomp.

The following code will leave a blank line at the end of <pre> blocks when the HTML is rendered: 

$ perl -e '
    my $insert = <<EOF;
line1
    line2
line3
EOF
    print "<pre>$insert</pre>";
'
<pre>line1
    line2
line3
</pre>

chomp to the rescue: 

$ perl -e '
    chomp(my $insert = <<EOF);
line1
    line2
line3
EOF
    print "<pre>$insert</pre>";
'
<pre>line1
    line2
line3</pre>

It can fix lots of annoying problems like that; not just <pre> blocks.
