Code clean up in "formatting.php" file.

Just pure fromating changes, one function change - shorther form of argument.

patch introduces bugs in functions like _make_email_clickable_cb(), where you've changed the type of quotes.

quite frankly, though, I'd suggest this gets closed until the huge load of commit candidates get looked into:

​http://core.trac.wordpress.org/report/9

there are hoards of them, and the odds are that a big patch like this might additionally break a few of the patches.

patch is broken. please re-open at some point in 2.9
