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.

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big>
<blockquote> <br /> <dd>
<dl> <dt> <em> <font>
<h1> <h2> <h3> <h4>
<h5> <h6> <hr /> <i>
<li> <nbsp> <ol> <p>
<small> <strike> <strong>
<sub> <sup> <table>
<td> <th> <tr> <tt>
<u> <ul>
-
Snippets of code should be wrapped in
<code> tags not
<pre> tags. In fact, <pre>
tags should generally be avoided. If they must
be used, extreme care should be
taken to ensure that their contents do not
have long lines (<70 chars), in order to prevent
horizontal scrolling (and possible janitor
intervention).
