[support] can i hook a hook?

[sebastian]

Hi Larry,

Thank you so much for replying to my query.

So if my contrib module doesn't offer an _alter() (and it does not) my 
only option is to hack the module? [or worse, use jquery to alter the 
output]

The module is question is nodeasblock and the function implements:

nodeasblock_block ($op = 'list', $delta = 0)

It makes theming decisions in it's operation, which I need to alter. 
Namely it decides that the $node->title should be:

l($node->title, 'node/'. $node->nid)

I need to strip the <a href> since I don't want my block to be clickable 
and lead to itself.

In other words:

'subject' => l($node->title, 'node/'. $node->nid),

will just become

  'subject' => $node->title,

I can hack the module, but that seems like a "no-no"

Thanks!

Sebastian.
