tg 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 ☹

in <CABNd6wz3SSRWamUNQ-BNcp7z0pthOR156=Zy3qBYmXhTjvoYsg@mail.gmail.com> but

<CABNd6ww7zFUQ4Ho2zQQzQyERy==8Hqg_y12Acmj1sF6ka4b4KQ@mail.gmail.com>:

when completing, always replace the olen text with the new one, and only
then take the length of the x_expand()ed nlen text to compare and check
whether to set completed=true; this also means:

$ ls foo\+/<tab>
          ↓
$ ls foo+/

this matches reality even better and saves us a couple of string traversals

Hunk 1: “Also, I found that x_escape() does funny things to sequences
of backslashes” which was caused by improper quoting; use an empirical
list of chars to escape (only 0x20‥0x7E, everything else is SOL anyway)

all cases; handle these cases (and break 0x02 in filename)

tg 2cfc3e5c3d mksh R40 Release Candidate 1
Testsuite:
• add new need-pass: {yes|no} attribute, default yes
• exit with 1 if a need-pass test failed unexpectedly
  idea by Kacper Kornet <draenog@pld-linux.org>
• mark utf8bom-2 as need-pass: no
Infrstructure:
• add housekeeping function for making a tty raw
• switch functions with unused results to void
• struct op: u.charflag contains last char of ;; in TPAT
• var.c:arraysearch is now a global function
Language:
• add ;& (fall through) and ;| (examine next) delimiters
  in addition to ;; (end case) as zsh extensions, because
  POSIX standardised on ;& already
• add -A (read into array), -N (read exactly n bytes),
  -n (read up to n bytes), -t (timeout) flags for read
  from ksh93
• allow read -N -1 or -n -1 to slurp the entire input
• add -a (read into array the input characters) extension
  specific to mksh to read, idea by David Korn
• add -e (exit with error if PWD was not set correctly
  after a physical cd) to cd builtin, mandated by next
  POSIX, and change error codes accordingly
Rewrites:
• full rewrite of read builtin and its manpage section
• add regression tetss for most of the new functionality
• duplicate hexdump demo tests for use of read -a
• use read -raN-1 in dot.mkshrc to get NUL safe base64,
  DJB cdb hash and Jenkins one-at-a-time hash functions
