Duplicate code oddness in wp_insert_attachement

[Otto42]

Just noticed this bit of code in SVN:

`
if ( isset($to_ping) )

$to_ping = preg_replace('|\s+|', "\n", $to_ping);

else

$to_ping = ;

`

...is duplicated in the wp_insert_attachment function. Line numbers 1345 and 1363.

Accidental copy/paste, or is there a reason for this that is cleverer than my current ability to fathom?

(In [6086]) Remove duplicate code from wp_insert_attachment(). Update to use sanitize_post. Props Otto42. fixes #4946

Did some more cleanup while I was in there.
