b41a72ac2e add new builtin “realpath” calling realpath(3) on its argument, skipping
over “--” for compatibility to Debian realpath(1) and possibly busybox’

4e4ede2442 fix for $HOME with trailing slash (do not expand then either… we could just
strip it, but that might have other problems, better is to use realpath(2),
e.g. via readlink(1), for normalisation, or have the sysop fix it)

XXX make realpath a builtin?

6be5205b36 mksh:
* initialise the integers PPID, OPTIND, RANDOM, SECONDS, and TMOUT to base-10
* bring back PGRP as base-10 integer to the process group via getpgrp(2)
* initialise USER_ID as base-10 integer to the effective user id as retrieved
  from geteuid(2) = $(id -u)
* use $USER_ID in dot.mkshrc instead of spawning an id(1) process
  -> dot.mkshrc,v 1.34 now requires mksh R34
* convert more int to bool where appropriate
* remove dead code - getpgrp(2) cannot fail
* sync manual page to reality
* bump to mksh R34(beta) - feature freeze

XXX check if our_pgrp in jobs.c is still really needed, the setpgid call
XXX probably just makes us our own pgrp leader, and we might have to use
XXX and update kshpgrp accordingly - need feedback/help here but I think
XXX this simplification should be possible if I grok the code correctly.

etc/profile:
* adjust to $USER_ID changes in mksh (speed-up here, too)

mksh.hts:
* sync changelog

e57f5fc09b • be friendlier to AT&T ksh: use only signed (standard) integers
‣ now, a “ksh93” just requires ‘function precmd { :; }; set -o emacs’
    afterwards to get rid of the annoying error messages
  ‣ I could lose that with the following idiom:
    - PS1='$(precmd)…
    + PS1='$(typeset -i e=$?; typeset -f precmd >&- && { (return $e); precmd })…
    but it didn’t seem worthwhile to me

92eb2aee78 • make sure “ls” is no shell alias:
‣ first alias ls=ls to define it (so that unalias won’t fail)
  ‣ then unalias ls
• don’t hardcode /bin/ls path

1086ebe83f • reduce number of readlink(1) / realpath(3) calls by caching the result of
running it on “~/.” (must be a directory) in a global readonly variable
• if readlink fails, use some more or less sane values (no idea what csh(1)
  does in these cases, maybe some feedback here?)
• optimise, while here

9533756d25 use precmd() to do the errorlevel-display dance, so that yofuh can disable
it more easily, and it got an actual use case

f632120cc2 by popular request, add
• dirs, pushd, popd like ports/shells/csh (Berkeley C shell)
• precmd, chpwd like ports/shells/zsh (Z shell)
and implement keeping ${DIRSTACK[0]} up to date via chpwd()
instead of doing it on entry of pushd and dirs (so that it
can be used directly)

this is slow compared to earlier, but people seem to want it

b2d0d57468 change our coding style for shell:
we already do not 'function\nfoo\n{' for shell, like style(9) requires for
C programming, but 'function foo\n{' instead. however, we could treat the
function keyword as indentation initialiser and use 'function foo {' (on a
line for itself) – it looks different, unusual, but acceptable, and mksh's
own output (dumping with the “functions” builtin) does that too (although,
its indentation style sucks, but is legible enough)

c79cacdfa5 • from a MirOS point of view:
place most stuff from /etc/profile in /etc/skel/.mkshrc; admins must make
  sure to copy this file to users' homes on upgrade (benefit: non-login but
  interactive shells also get all the goodies); fix some quoting; simplify,
  reformat, change comments
• from an mksh point of view:
  slight internal changes in dot.mkshrc; external commands are now prefixed
  with “ulimit -c 0”; $TERM is defined; improvement in determining the host
  name (e.g. on Debian if a FQDN is not given); declare locals as such both
  in $PS1 and outside; remove superfluous quoting, quote properly; simplify
  hd alias, add rot13 alias; place RCS ID at the bottom

83c2ee87f4 • remove strcasestr.c, use home-grown implementation¹, call it stricmp,
and have it return an API-correct const char *
• enhance and stylify comments
• a little KNF and simplifications
• #ifdef DEBUG: replace strchr and strstr with ucstrchr and ucstrstr
  that take and return a non-const char *, and fix the violations
• new cstrchr, cstrstr (take and give const char *)
• new vstrchr, vstrstr (take const or not, give boolean value)
• new afreechk(x) = afreechv(x,x) = if (x1) afree(x2, ATEMP)
• new ksh_isdash(str) = (str != NULL) && !strcmp(str, "-")
• replace the only use of strrchr with inlined code to shrink
• minor man page fixes
• Minix 3 signames are autogenerated with gcc
• rename strlfun.c to strlcpy.c since we don't do strlcat(3) anyway,
  only strlcpy(3), and shorten it
• dot.mkshrc: move MKSH=… down to the export line
  to not disturb the PS1 visual impression ☺
• dot.mkshrc: Lstripcom(): optimise
• bump version

¹) side effect from creating API-correct cstrchr, cstrstr, etc.
   uses goto so it must be better ☻

tested on mirbsd-current via both Makefile and Build.sh

1c9a925139 rewrite stripcom/Lstripcom function, making use of the 'last command
of a pipeline is executed in a subshell' trick, don't use co-process
(because that's verbose twice in an interactive shell profile), move
the noglob block into the while and rid the redundant +o and local.

f1e8f970c4 * get dot.mkshrc sample from Debian mksh-27.4-2
* sync dot.mkshrc sample with FreeWRT r383
* add some stuff from src/etc/profile and contrib/samples/etc_profile
* sync the latter two with reality and shorten
* teach the user in the mksh installation instructions to install the sample

NB: the sample is also covered by the MirOS licence
