Calendar widget title markup displayed when empty

[joshstauffer]

For Calendar widgets, the widget title markup is output even if the title field is left empty. For instance, <h2 class="widgettitle"> <h2>

Conversely, when a Text widget title field is left empty, no markup is output.

here you go

I think that this is a great idea! In a few themes, I have had to filter the widget title like:

function mytheme_calendar_widget_title( $title = '', $instance = '', $id_base = '' ) {
	if ( 'calendar' == $id_base && ' ' == $title )
		$title = '';

	return $title;
}

I find that it is always necessary to do when the widget title has a background color applied. In the event that the user leaves the title blank, a weird square will appear above the calendar.

Patch works perfect. It not only is noticeable when the title has a background color but creates an awkward whitespace when it is empty due to the line-height 18px being applied to the &nbsp;
