1. Make match_ignore_ascii_case! future-proof. …

   Change the usage syntax to require a comma on the last non-fallback arm,
   which is a [breaking-change].
   
   The old definition has started to emit a warning in recent nightlies
   and is likely to be an error in future versions:
   rust-lang/rfcs#1384
   
   The new definition is recursive to resolve ambiguities.
   Unfortunately this makes error reporting terrible:
   rust-lang/rust#31022
