SECURITY: Unbreak “set +p”, broken by OpenBSD ksh change.
...
TODO: I am seriously considering following Chet and changing
the way this works, by explicitly dropping privs unless the
shell is run with -p. Every other shell does it like mksh,
except Heirloom sh, which on the other hand doesn’t know any
explicit set -p or set +p (though it doesn’t know set +foo
for any foo either).
┌──┤ QUESTION: Do we need the ability to do this:
│ tg@blau:~ $ ./suidmksh -p -c 'whoami; set +p; whoami'
│ root
│ tg
If not, I’m seriously considering to drop set ±p as well,
only parse -p on the command line, with +p being the default,
and dropping FPRIVILEGED.
Thanks to RT for noticing and jilles for initial follow-up
discussion, as well as Chet Ramey for doing the sane/secure
thing instead of following Debian.

support n̲o̲t̲ fork(2)ing for -T (by prepending the tty with ‘!’); especially useful on Linux since our own setsid(2) is more annoying; gets rid of the need for oneit_lite and similar hacks; WARNING: also removes chown/chmod on the tty!

• Allow setting both -o posix and -o sh (although only in the same

command; setting one still unsets the other at first)
• Change subst_exstat to be conformant unless -o sh is set and -o posix isn’t

• New MKSH_BINSHPOSIX to accompany MKSH_BINSHREDUCED
• Sync lksh manpage precisely

if we find any, but not later; do not check on every read

for script shells by passing them in an environment setting, even if
we get a tty; interactive shells still check before each line is read…
