a09f05e77a /me is annoyed
I read, IIRC in the Cederqvist, that 'cvs tag' sets a sticky tag onto
the cwd… it doesn’t, apparently. (I actually like it better this way,
but one needs to know!)

883d9d99b3 switch ${%foo} to wcswidth-like behaviour – slightly problematic, and
the “set +U” case isn’t even handled

committed to branch because I’d like to get more input on this, for now

2094e3f25c since we have wcwidth anyway, expose it as ${%strvar} to the user, iff
utf8-mode is enabled (otherwise it'll be a synonym for ${#strvar} aka
the number of octets in it)

6fcacf577d make tab completing filenames with ':' '=' '$' '`' work as well as
others (colon and equals sign need to be simply escaped, while dollar
sign and accent gravis need double escaping like opening square brak-
ket did back then); add = to C_QUOTE to simplify (doesn't break any-
thing) and sort these strings asciibetically while here

4392aced96 the capability to get array indicēs (keys), Korn shell style
bash4 doesn’t have it at all, despite knowing associative arrays
zsh does it………… differently and weird

this is for indexed arrays, as mksh doesn’t have associative arrays
but it should help ☺

4ccdfc8508 much better solution: save tablep and hash value¹ in the struct tbl entry
① also saves time during texpand :D

XXX this doesn’t work well with the current indexed-array implementation

7240c843ce this is a rather stupid diff: give ktsearch/ktenter the capability to
return information needed to do a real ktremove instead of the pseudo
ktdelete operation which merely unsets the DEFINED flag to mark it as
eligible for texpand garbage collection (even worse, !DEFINED entries
are still counted)

0c2555e5c2 utfincptr is a no-op in !UTFMODE, yet I had the “if (UTFMODE)” not only
commented out for mksh R38* but also used // denoting a temporary, de-
bugging-only, code exclusion which never should have been in the wild

b6ce748064 • remove “#if 0” and “#ifdef notdef” style old debugging code
• expose “#ifdef MKSH_MIDNIGHTBSD01ASH_COMPAT” just in case they decide to
  require it and show it in the ksh version automatically

fix the regression test’s results while here, which have been
  broken since cid 10049D9BE5254CE65B8
• get rid of separate copyright file which was intended for De-
  bian; track down commits in all files of oksh-mirbsd and mksh
  to get correct copyright years per-file, as is BSD custom

cc783807d3 this began as a one-word change to the spec (manpage): that
${foo:1:2} operates on characters ipv bytes – which means:
‣ set +U: octets
‣ set -U: MirOS OPTU-8 characters

for consistency I also adapted ${#stringname} to deliver the
length in characters ipv bytes; more may follow; for example
I’d like a way to expose the string width.

you can already get the MirOS OPTU-16 of a character in the
WTF-8 (「set -U」) mode with something like
│ typeset -Uui16 -Z7 x=1#${stringname:position:1}
which will correctly use the PUA EF80‥EFFF mapping for octets.

due to this being an incompatible change, bump to R38

also change the unicode-hexdump sample regression test and
add two news for ${x:1:2} and ${#x} checks in A/W mode ☺

b20f49adae patch from oksh (except manpage, I'll merge that later):
pass "xerrok" status across the execution call stack to more closely
match what both POSIX and [18]ksh.1 already describe in regards to set
-e/errexit's behavior in determining when to exit from nonzero return
values.

specifically, the truth values tested as operands to &&' and ||', as
well as the resulting compound expression itself, along with the truth
value resulting from a negated command (i.e. a pipeline prefixed !'),
should not make the shell exit when -e is in effect.

issue reported by matthieu.
testing matthieu, naddy.
ok miod (earlier version), otto.
man page ok jmc.

31d1499219 * back out almost all of the memory allocator related changes, as aalloc
was hard to type and hard to fix, galloc is also hard to fix, and some
  things I learned will probably improve things more but make me use the
  original form as base (especially for space savings)
* let sizeofN die though, remove even more casts
* optimise, polish
* regen Makefiles
* sprinkle a few /* CONSTCOND */ while here

01b54f1fd5 I _think_ this implements ${foo/bar/baz} logic (bar is a glob pattern)
todo tomorrow:
• test case (compare with e.g. GNU bash)
• manpage
• version bump

sqchar is a bit ugly, but \/ must be preserved, as we don’t get wdencoded
strings later on in the process (eval.c CSUBST) and I didn’t want to have
an implementation like ${foo: 2: 3} this time

c1c939e340 • fix memory leaks found by coverity
from netbsd via oksh
  we had the NULL pointer deref already fixed
• avoid a bogus not-setting the return value of edit.c:x_file_glob()
  introduced by the above change in oksh
• escape ? as well (but not ] because that’s wrong)
  reminded by cbiere@netbsd via oksh
• Unsetting a non-existent variable is not an error. See
  http://www.opengroup.org/onlinepubs/009695399/utilities/unset.html
  report from Arkadiusz Miskiewicz; fixed based on
  http://cvs.pld-linux.org diff via oksh but modified slightly
• Be more smart waiting for input for non-interactive scripts.  Fix
  based on a diff from debian:  see their bug#296446 (via oksh)
  modified slightly
  this also fixes cnuke@’s “mksh busy loop” problem, for which I never
  received a bug report, but the Debian bug page contains a set of two
  scripts to reproduce this before (and no longer after) this commit
• some KNF

ca17798533 this is bash compatibility week, and by suggestion of actual users,
namely Dr. Robert “Pfeffer” Arnold (in this case, in FreeWRT), make
a half-completed attempt at implementing ${foo:2:3} substring evals
(of course, negatives can't work right now and that the numbers are
in face expressions is something I only read later too – this is to
be revisited later, but it's already late)

don't depend on this behaviour yet though

a84655e3e0 fix Coverity CID #8, #9
it's wrong to use strchr(s, 0) to look for the NUL byte, because in some
