about how and when the display is redrawn by reverting one
bool back to an int, as it’s used as a counter (hm, should
be an unsigned I guess but…)
on the other hand, xlp_valid should’ve been a bool, make it so
expansion completion; problem analysis and solution draft by Andrew
Kudryashov (thanks a lot!); this fix instead re-uses existing code
for solving the problem with multiple matches
debugged using “make d dr” targets, yay!
XXX we could track whether tty_fd has already been successfully opened,
XXX the ttystate initialised, and then just never close it unless it is
XXX necessary, then we can keep COLUMNS/LINES accurate in scripts, even
in <CABNd6wz3SSRWamUNQ-BNcp7z0pthOR156=Zy3qBYmXhTjvoYsg@mail.gmail.com> but
by a different (cheaper) method than the one in his patch from message-id
<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)
Hunk 2: “and "\*" will be appended” was actually correct, but not in
all cases; handle these cases (and break 0x02 in filename)
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
