This version now uses update.module, if it is activated, to fetch real project names, so instead of having a link like this:
dopl.module
you will now have a link like this:
Drupal.org project link filter
If a such a project does not exist, it simply ignores it.
If update.module is disabled, the filter will turn all the usable patterns it finds, and turns them into links, regardless of whether a project of that name really exists.
