(yeah, that's what you get from developing with a
16-bit MS-DOS(R) executable of your favourite text editor)
* lex.c, mksh.1: do not print the delimiting character for
not-to-be-counted character sequences (i.e. ANSI escapes)
in prompts any more, mostly because ASCII 01h is printable
on both Interix and Cygwin and I'm lazy
(this also fixes prompt width counting if a printable character
such as 'x' is used as delimiting character)
* lex.c: through printing the prompt character by character,
also print the delimited sequences if skipping, fixes some
prompt redrawal not honouring colours stuff while not totally
redrawing the entire prompt
