Incomplete documentation for hook_menu

I added in a description of 'title callback' and 'title arguments'. I don't think there is a 'description callback'.

However I'm concerned that there is no explanation of how the wildcards work when they are passed on as arguments. This cost me a good bit of time the other day when encountering it for the first time and will baffle many others too I'm sure. The current text:
Integer values pass the corresponding URL component (see arg())
does not come close to explaining the way the wildcards are processed via _load functions.
I'm not sure where to add that into the doc though.

Minor, but that patch is slightly inconsistent with the use of spacing between sentences.

Ah. Alignment fix attached.

IMO, this one was thoroughly hashed out and should now be committed.

I can't find the issue queue issue, but this has already been fixed.

The new text added by this patch:

+ *   - "title": Required (unless title callback is provided). The untranslated 
+ *     title of the menu item.
+ *   - "title callback": The function to call to modify the title.  Takes $title,
+ *     the title, as a parameter if no title arguments are defined.
+ *   - "title arguments": An array of arguments to pass to the title callback
+ *     function.  Integer values pass the corresponding URL component (see arg()).

The current Drupal 7 menu.api.php text:

 *   - "title": Required. The untranslated title of the menu item.
 *   - "title callback": Function to generate the title, defaults to t().
 *     If you require only the raw string to be output, set this to FALSE.
 *   - "title arguments": Arguments to send to t() or your custom callback.

It was fixed in this CVS patch: http://cvs.drupal.org/viewvc.py/drupal/drupal/modules/menu/menu.api.php?...
