c700693d11 Add “unset foo[*]” mksh extension, which allows to unset the *contents*
of foo[0] (but not its attributes), and the rest of the array, so that
later “set +A foo bar” will set foo[0]=bar but retain the attributes.

This is important, because, in the future, arrays will have different
attributes per element, instead of all the same (which, actually, is
not entirely true right now either, since “unset foo[0]” will not mo-
dify the attributes of a foo[1] existing at that point in time), where
foo[$newkey] will inherit from foo[0], but typeset foo will only affect
foo[0] no longer foo[*] in the future. (The rules about typeset=local
will still apply, as they affect creation of variables in a scope.)

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

dc98ec23a6 do not use PATH_MAX on GNU/Hurd (even if it *was* defined), but use
some glibc-only functions that don’t require its use instead

549888a183 while testing haserl-0.9.26 on MirBSD, I discovered that the echo builtin

33b9f8b666 * rename "set -o posix" (FPOSIX) to "set -o sh" (FSH) because it's not
just a "somewhat more POSIX" but also a "/bin/sh legacy kludge" mode
* consistently capitalise POSIX and SUSv3/SUSv4 (same as AT&T ksh) and
  Bourne shell

a59d14b565 further optimise and simplify the handling of $RANDOM, reads and writes
to it are now either arc4random or rand/srand, but srand retains the old
state; set +o arc4random is no longer possible, but if it's there we use
arc4random(3), if not, we use rand(3) for $RANDOM reads; optimise special
variable handling too and fix a few consts and other minor things

1a28786229 * shrink MKSH_SMALL even further by removing functionality like
some GNU bash extensions (suggested by cnuke@) and bind macros
* make the random cache more efficient (and the code potentially
  smaller, although we have a new implementation of the oaat hash
  function, alongside the old one, now) and pushb only if needed
  (i.e. state has changed or user has set $RANDOM, but not onfork)

e622d80394 replace pdksh’s get_phys_path() and do_phys_path() with my new

tg
31e02e59f7 add a do_realpath() implementation replacing the use of the external
libc function realpath(3) which may not be available on the target
system; compile the realpath builtin unconditionally

looks fine to me, but review is appreciated; this is (very) lightly
based upon MirBSD libc’s realpath(3) and pdksh’s get_phys_path()

9b8d4023fa … but since I liked the bonus of having the hval stored so much, merge
it with the array index; var.c says that
│ 1244         /* The table entry is always [0] */
so that we can have a special flag and a union which stores hval for
the table index, the array index otherwise (coïncidentally *hint hint*
they have the same size)

4ccdfc8508 much better solution: save tablep and hash value¹ in the struct tbl entry

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)

ca1f967a45 • use Jenkins’ one-at-a-time hash for mksh keytabs, as it has
much better avalanche and no known funnels
• improve comments
• fix some types (uint32_t for hash, size_t for sizes)
• optimise ktsort()

no functional change, I think

0e1266ef90 While mksh R39 builds fine on MirOS #7s8E on my trusty sparc, pgcc 2.95.3

  for specific OSes, bad, instead of using mirtoconf checks proper) and
  "conditions correct?" (if I'm not entirely sure if that #if catches all
  cases and no false positives) where I can see it by grepping immediately
