change the behavior of Esc Esc [3-digit number from 000 to 255] so that

it enters the byte with that value regardless of whether we're in UTF-8
mode or not, and update the help text to mention this; this will allow
searching for and replacing raw bytes with their equivalent multibyte
sequences as entered using verbatim input
