What does menu blocks "Block title as link" option do? The Menu block module has an option on each block titled "Block title as link". My interpretation of the description combined with some testing, is that if I leave the "Block title" setting out, the name of the menu will be used as the block title, and it should also be a link to the currently viewed menu item.

However, when I check the option and try it, I never get any links. I've been trying to follow the code, but I couldn't make any sense of it, so I believe my expectation on the functionality is wrong.
For me it doesn't show the menu name, but the link to the parent menu item of the block. IE with a menu hierarchy like this:

&lt;Main Menu&gt;
-- a
---- b
------ c
------ d
------ e
-- f
-- g


If the block looks like this:

Title
c
d
e


Then having the block title as link makes the title a link to menu item b.
