“Link to this page” widget

blog.anta.net — I I recently added a “link to this page” toy to www.anta.net. Using JavaScript and the Apache mod_include module, the widget implements a text input containing the HTML for creating a link to the page in question. The basic idea is a no-brainer, but since I had to sit down for a while to entitize and escape stuff, I might as well share the snippet.
