/* ./. adhere more closely to POSIX even when undesirable */
To solve the incompatibility issues between mksh-current, old mksh versions and vendor pdksh versions, re-introduce FPOSIX alongside FSH. The semantics are now: ‣ set -o posix ⇒ • disable brace expansion and FSH when triggered • use Debian Policy 10.4 compliant non-XSI “echo” builtin • do not keep file descriptors > 2 to ksh ‣ set -o sh ⇒ • set automatically #ifdef MKSH_BINSHREDUCED • disable brace expansion and FPOSIX when triggered • use Debian Policy 10.4 compliant non-XSI “echo” builtin • do not keep file descriptors > 2 to ksh • trigger MKSH_MIDNIGHTBSD01ASH_COMPAT mode if compiled in • make “set -- $(getopt ab:c "$@")” construct work Note that the set/getopt one used to behave POSIXly only with FSH or FPOSIX (depending on the mksh version) set and Bourne-ish with it not set, so this changes default mksh behaviour to POSIX!

• more comment and int→bool cleanup, add and improve some comments • in interactive mode, always look up {LC_{ALL,CTYPE},LANG} environment variables if setlocale/nl_langinfo(CODESET) doesn’t suffice • add the ability to call any builtin (some don't make sense or wouldn't work) directly by analysing argv[0] • for direct builtin calls, the {LC_{ALL,CTYPE},LANG} environment variables determine utf8-mode, even if MKSH_ASSUME_UTF8 was set • when called as builtin, echo behaves POSIXish • add domainname as alias for true on MirBSD only, to be able to link it • sync mksh Makefiles with Build.sh output • adjust manpage wrt release plans • link some things to mksh now that we have callable builtins: bin/echo bin/kill bin/pwd bin/sleep (exact matches) bin/test bin/[ (were scripts before) bin/domainname=usr/bin/true usr/bin/false (move to /bin/ now) • drop linked utilities and, except for echo and kill, their manpages • adjust instbin and link a few more there as well
