[wp-hackers] Code formatting

After reading this I looked at the Codex again and saw that it's not 
explained for round brackets neither. In the code there are both 
versions

---
current_user_can('edit_posts')
do_action( 'in_admin_footer' );
---

(copied and pasted from the core code).

To be consistent these should be written without spaces if it's a pure 
string and with spaces if it's a variable. What if it's a mixture, like 
function('string', $var); I would vote for spaces.

I didn't want a long dicussion but after I started this I can't stop 
;-) After we came to a consensus I'll update the Codex.
