A pane's ctl takes acme's ctl words, done by the files that replace them

name, put, clean, dirty, del, delete, dot=addr, addr=dot, limit=addr, mark, nomark, show and cleartag were unknown control messages. Each is now done by the file or builtin that replaces it (name, Save, dirty, Del, a Del that does not ask, dot and addr and limit, mark, the tag), checked with the rest of the write before any runs; dump, dumpdir, font, menu and nomenu are refused, EINVAL, saying where pardes does it or that it has no such thing.
