POSIX builtins

X-seq: zsh-workers 1966
From: Zoltan Hidvegi <hzoli@xxxxxxxxxx>
To: zsh-workers@xxxxxxxxxxxxxxx (Zsh hacking and development)
Subject: POSIX builtins
Date: Wed, 14 Aug 1996 03:17:59 +0200 (MET DST)
The patch below adds a new POSIX_BUILTINS option.  Please test it before I
put it into zsh-3.0.0.  The patch to the manual should tell everything
about this option.  This is turned on for both sh and ksh emulation mode
(bash, pdksh and ksh93 behave this way).
