I was wondering if anyone knows how to insert content after the numbers when the
nextpage tag is used? What I want to insert is a comma or vertical bar separator between the links (or maybe list-organize them). The documentation seems to suggest those links are comma-separated, but they are not.
If an argument (parameter?) isn't known, can someone tell me which line of which file I need to edit to make this possible please? I've hunted through the template function files, and I think it's in the posts functions file, but I'm unsure where.
Ideally I'd like to do this in the theme files, but if I can't, I will edit the core files for this particular installation. I just want to make it so... for improved accessibility.
