Bug in trigger module behavior

The documentation for hook_hook_info states that the return value should be:

Return value

• A nested array. The outermost key defines the module that the triggers are from. The menu system will use the key to look at the .info file of the module and make a local task (a tab) in the trigger UI.
• The next key defines the hook being described.
• Inside of that array are a list of arrays keyed by hook operation.
• Each of those arrays have a key of 'runs when' and a value which is an English description of the hook.

However, the actual behavior is (Change is underlined)

Return value

• A nested array. The outermost key defines the module that the triggers are from. The menu system will use the key to look at the .info file of the module and make a local task (a tab) in the trigger UI.
• The next key is the module name again..
• Inside of that array are a list of arrays keyed by hook operation.
• Each of those arrays have a key of 'runs when' and a value which is an English description of the hook.

I have attached a patch that I believe rectifies this.

I should also mention that all the documentation I could find for this feature assumes that the first two keys do not have to be identical.
