    sh: Sync with FreeBSD
    
    * Recognize "--" and explicitly reject options in wait builtin.
    * Mention possible ambiguities with $(( and ((.
    * Write as much into the heredoc pipe as possible, to avoid forking.
    * Don't modify exit status when break/continue/return passes !.
    * Document a few expansions for the $PS1 and $PS2 environmental
      variables.
    * Don't consider jobs -s/-p as reporting the status of jobs.
    * Improve error handling in read builtin.
    * Use O_CLOEXEC and F_DUPFD_CLOEXEC instead of separate fcntl() call.
    * Remove linked list of stack marks.
    * Allow multiple operands in wait builtin.
    * Return status 127 for unknown jobs in wait builtin.
    * Do not read from stdin if an error occurs during -i -c cmd.
    * Remove mkinit.
