Consolidate link delimiter functions #59
Description
We currently use several separate functions to insert delimiters between posts, pages, archives, and images. These could be consolidated into a single, simplified function that uses a case switch and is able to pass through a custom delimiter glyph or entity.
The affected functions are:
delim_post_link()
delim_posts_link()
delim_comment_link()
delim_image_link()
The new function should be named using the tersus_ prefix and use a function_exists wrapper similar to other pluggable theme functions.
