Markdown editor inconsistent with osm.org (underscore handling)

[RicoElectrico]

If the user has _ in their name, this fomats the whole message in italics in the editor. The parser at osm.org is somewhat smarter and ignores such occurrences.

This is indeed an issue when there is an underscore (_) in the username.

I'm relying on highlight.js for this.
I'll see if there is a workaround possible.
