also, bump to R50 beta, due to today’s language changes

495b798893 improved OE reporting for newer Darwin/OSX, by Ryan Schmidt <ryandesign@macports.org> 2014-05-27 13:41:53 +00:00

033e1f4b9e fix LP#1277691 (“nameref RHS not syntax checked”) and the inability to 
use errorf() while nameref states were being changed (by almost completely
eliminating the global variable) and the readonly first array variable
bypass (typo/refactoro); also, whitespace, one int → bool, and add a
comment wrt. the parser rewrite talked about with igli during a fever ;)

2e7509548a integrate latest changes from oksh: Wed Sep 4 15:49:19 2013 UTC by millert 
Add a proper suspend builtin that saves/restores the tty and pgrp
as needed instead of an alias that just sends SIGSTOP.  Login shells
may be suspended if they are not running in an orphan process group.

fda010d8de 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.

  others game; sync manpage

  name and so can’t be overridden but is unlikely to be used otherwhere
  and not strictly permitted (by POSIX) anyway
