16854	wp_query does not handle multiple exclude author properly	commentluv		"when making a query with $args containing 

{{{
'author' => '-2,-3,-4'
}}}

line 2008 of wp-includes/query.php only uses 1 element of the array that is created from the 
{{{
$q['author'] string
}}}

{{{
 $q['author'] = explode('-', $q['author']);
 $q['author'] = (string)absint($q['author'][1]);
}}}

I have attached a patch that works with 1 or more excluded authors

essentially it, implodes the array back into a string of author ID's rather than selecting only element [1] of the exploded array

{{{
$q['author'] = explode('-', $q['author']);
$q['author'] = implode('',$q['author']);
}}}
