* node.c (dump_node): add today's knowledge. "init arguments (m)" and
"init arguments (p)" of compile.c indicates a Ruby code that evaluates multiple assignments that is in method or block parameters: def foo((m1,m2), (m3,m4), *r, (p1,p2), (p3,p4)); end The former (init arguments (m)) evaluates the multiple assignments before rest argument, that are (m1,m2) and (m3,m4). The letter (init arguments (p)) does ones after rest argument, that are (p1,p2) and (p3, p4). git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@32596 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
