Show content type help text also on edit forms

Seemed to do the trick here. Thanks a lot.

Applies cleanly, seems to work, code is simple and looks correct.

For 6.x, at least, I think it's fine not check if $node was loaded, since for a non-existent node you'll get sent to drupal_not_found() before this code is called.

This can be written in a more compact fashion. Code should not repeat.

Steven, I though about that too, but it wasn't obvious to me how to make it not repeat without an if/else block that was very convoluted.

There is a more fundamental problem here. There is no guarantee that the help hook is only called once on a page, and the page level help text is requested. Admin pages use the help hook to build up a dynamic menu item list of modules providing help, so we are not limiting the help hook to provide page help. These if's does not check if we have anything in $section which has something to do with what arg()s return. It probably did not show up because these arg() checks are not conflicting with the admin page menu building, which is the only other core use case for non-page level help calls, but you get the idea.

So a better solution would be to pass on the real path value to check with, not relying on that we might get called for the page help.

Is this an issue any more?
