Changes with Apache 2.5.0



  *) mod_rewrite: Add an internal RewriteMap function named "sleep"

     that always returns an empty value and sleeps for the specified

     interval. [Eric Covener]



  *) mod_rewrite: Treat a RewriteRule substitution that expands to

     "-" to behave as if a literal "-" was used in the RewriteRule

     (no substitution). [Eric Covener]
