WordPress mu-plugin that replaces colon with dash before saving content to database.

Description

Colon is allowed in the fragment part of a URI according to RFC 3986 and is allowed in id and name in both HTML4 and HTML5. Despite these facts, WordPress removes everything up to and including the colon when a colon is used in a fragment of a relative or a protocol-relative URL. An example when this cause problem is when HTML generated by Markdown Extra is used, since colon is used in fragments to both link to the footnote (e.g. #fn:1) and link back (e.g. #fnref:1). Thus the need for this "hack" which replace colon with a dash in id and name attributes, and in href attributes that are relative (i.e. not starting with http://, https://. This is done before KSES runs and the post content is saved to the database.
