Subject: [PATCH] - the $case macro used by r6rs:case and case now
 unconditionally trims   redundant keys and expands into exclusive-cond rather
 than cond.   it catches references to => before expanding into exclusive-cond
   to avoid supporting => as an undocumented and useless extension   of the
 case syntax.  the r6rs:case and case macros now require   multiple clauses
 rather than leaving the enforcement to exclusive-cond,   and the
 exclusive-cond macro now requires multiple clauses rather   than leaving the
 enforcement to cond.     syntax.ss,     4.ms, root-experr*, patch*
