609b311919 more low-hanging fruits for EBCDIC; notes: 
• ord() new, From: Daniel Richard G. <skunk@iSKUNK.ORG>
  ‣ used in some places
• (c - '0') → ksh_numdig(c)	# may take *x++ argument
• (c - 'A') → ksh_numuc(c)	# may NOT take *x+= argument
  ‣ idem for ksh_numlc(c) and 'a'
  ‣ these need changing for EBCDIC
  ‣ add testsuite for this
• use macros more, they exist already often
• use digits_lc[foo] instead of ('0' + foo), especially for letters
• caught another ksh_eq case…
• also caught a maybe-UB overflow check, but we don’t have TIME_T_MAX ☹

65f9b93926 ordinarily, lineno must be mksh_uari_t, but edit.c most of all isn’t ready, 
so we mitigate a bit (in var.c mostly) and tweak another type already, and
add some checks (mksh_{,u}ari_t must fit into {,unsigned }long) and print
line numbers with %lu already

e1cda74d04 SECURITY: fix integer overflows related to file descriptor parsing 
bug initially found by Pawel Wylecial (LP#1440685)
additional bug found and suggested fix by enh (elliott hughes)

This commit also renames struct ioword.flag to ioflag to disambiguate
it from other members named “flag”, changes it to an unsigned type,
and packs ioflag and unit into shorts each, to make the struct smaller
(aligned even: 16 bytes on 32-bit systems) and reviews some of the
code involved in fd handling, though there wasn’t much to be found.

c10e5bd237 reduce amount of .bss memory needed; initialise via AEDIT at x_init

247e20c524 • Completely overhaul prompt length calculation and 
prompt display routines; make Emacs and Vi share
  code, permitting reducing of duplication and code
  removal as well as more consistent behaviour; put
  some common code into shared helper functions, too
• New x_adjust() logic (Emacs mode): when determining
  what portion of a line to render use a much more
  sophisticated algorithm and try to fill up ⅔ of the
  total screen width (with line and prompt both) also
  as wished from Steffen Daode Nurpmeso

74e2ef8b0b one more int → bool; mention “set -o sh” may (on raare OSes) be enabled 
automatically (and it differs between targets); test MidnightBSD 0.1 ash
compat code and adjust the testsuite so it passes with it enabled

e21a2166f7 use a different approach to the $"…" problem: 
take the states that may open a string, only permit them by virtue of
moving the code out of Subst: to handle $+" and $+' at all; then add
S[Q]BRACE to that

side benefits:
• clearer, cleaner code flow
• smaller code
• better “business logic” ☺
• defuses one heavy use of duff’s device a bit
