Simple PHP Space Removal

Job Description

The Problem:

I have a custom filter for WordPress' wp_link_pages which allows both next/previous links and pagination to be used. However, I have an extra linked space in front of 'Next page' I can't seem to get rid of. I would like to not only remove this space (while maintaining well-coded php) but to remove all spaces from WP_LINK_PAGES so I can simply assign spacing via CSS.

To receive the payment I need you to do the following:
View my code and problem, then provide me with a modified code which removes the extra space in front of "next pages" and the spaces generated between each paginated and next/previous link so I can assign spacing via CSS only. More simply put, remove all the spaces!
