< and > are not changed to &lt; and &gt; in source
highlightning mode if they are on a comment line starting
with //.

The story how I found out this must be told... Besides, it's
also an example of how to reproduce the bug.

I wrote an example how to display tree structures in tables
and for completeness sake did also intended from right to
left for hebrew or arabic speaking php-users. After finding
an annoying misbehaviour in Netscape, I put these lines in
the source:

	// Netscape seems not to like this...
	// $tmpstr .= "<td colspan=$span width=$pixels>";
	$tmpstr .= "<td colspan=$span>";

Then, after submitting the example to Berber's example pages
and going back to look at it, I found it to be in two columns
and you guess where the split to next cell happened... Now,
let's see how this bug report looks out. :)
