CVS commit: src/bin/sh

["Robert Elz" <kre%netbsd.org@localhost>]

Module Name:    src
Committed By:   kre
Date:           Mon Jul 24 14:17:12 UTC 2017

Modified Files:
        src/bin/sh: jobs.c option.list sh.1

Log Message:
Implement the "pipefail" option (same semantics as in other shells)
to cause (when set, which it is not by default) the exit status of a
pipe to be 0 iff all commands in the pipe exited with status 0, and
otherwise, the status of the rightmost command to exit with a non-0
status.

In the doc, while describing this, also reword some of the text about
commands in general, how they are structured, and when they are executed.
