(Karl Eichwalder ke@gnu.franken.de):
Also, "fragment links" are not supported, you know, these "http://example/page.html#fragment" pointers.
Actually they are; have been for a long time. But the ability to make the link _target_ has been disabled until we can agree on a better syntax for it.
My current favorite suggestion is that second-level headings (H2) should automatically become link targets.
