Untrimed space in styles in video shortcode.

[danielpietrasik]

The error is in wordpress/wp-includes/media.php file, line
2590:

$width_rule = sprintf( 'width: %dpx; ', $atts['width'] );

In style attribute there is a single, untrimed space which creates string like:

<div style="width: 640px; " class="wp-video">
