slightly optimised and, more importantly, much more consistent (use only
one set of CTRL, UNCTRL, and new ISCTRL macros) C0 and DEL handling; the optimisation only works for 7-bit ASCII, so those places 8-bit must pass intact have an added check also, while here, remove an editor oops (‘;’), oksh rcsid sync (they did accept I was right wrt. set -e), int → bool, and code merge/cleanup
