Del and Delcol refuse unsaved text once, as acme's do

acme's Del asks winclean first and Delcol colclean (exec.c del, delcol):
unsaved text is warned about, and the same word again closes. pardes closed
at once. Both now refuse once through the one-warning-per-word mechanism
Exit uses, from keys, tags, exec and ctl alike. A pane dirty only by a
rename, or an empty one that never held a file, has no text to lose and is
not asked about, and a scratch or a command's output under 100 bytes is not
either, as acme's winclean passes a small unnamed window.
