Unless some thing has changed with c, changing  to   is a nul edit - it change nothing about how the template works or how the page looks. The template assumes that the number sign is associated with the first volume of the title. Both create the same link and both render as "Final Crisis #7".

If the change results in a nul edit, the it shouldn't be done.

That's not to say there aren't cases where links to issues shouldn't be edited. Normally though those are cases of applying to replace a longhand link.
