Produces a bold wikilink for denoting world records.
Usage
{{WR|sport}}
The sport parameter is optional; if present, it changes the link to [[List of world records in sport]] instead of to the default
World record article. For example {{WR|athletics}} results in a link to
List of world records in athletics.
For performances that equal an existing world record, set the named parameter eq to any non-blank value. For example, {{WR|swimming|eq=1}} results in =WR.
