Update: My, what was I thinking...

Use the version of the internal and external links with "quotes"!

With links like these:	Anchors like these can be included in the section where the link should point to:
<a href=#anchorname>Text Text Text</a> <a href="#anchorname">Text Text Text</a>	<a name=anchorname>Text text text</a> <a name="anchorname">Text text text</a>

Avoid using /index.pl, since that would stress the servers of the Perl Monks website too much, now or in the near future.

The most elegant solution so far to link to a named anchor in another node is this:
<a href="?node=954#regexdata">Regular Expressions</a>

Thanks to the high class (and serious) info from castaway and tye. Please prevent people like me to cause problems with the server (now or in the future).
