Whitespace between a href

I just updated to the latest version and found an “bug” came back. It seems that in my earlier version I removed the white space in the a href link. This solves an blank space on the front end code.

Would you be so kind to remove this in your original version too?

line 55: www-functions.php change from:

?>
<a
class="<?php echo esc_attr( $class ); ?>"
href="?add_to_wishlist=<?php the_ID(); ?>"

to:

?><a class="<?php echo esc_attr( $class ); ?>"
href="?add_to_wishlist=<?php the_ID(); ?>"

And the output is much cleaner ??
