Release Status: release

Description:
        After reading the documentation in "help shopt" I attempted to set
flags, for example, noclobber, by using "shopt -s noclobber", but got an
error message. I've found that I can do that by using "shopt -s -o
-noclobber" but that the help provided me no indication that the additional
"-o" was actually necessary.

Repeat-By:
        Using "shopt -s noclobber" (or any optname) instead of "shopt -s -o
noclobber).

Fix:
        I would suggest to change the help of shopt so that it says [-o
[optname ...] ] instead of [-o] [optname ...], and change the help where
relevant.

Thank you very much.
Yours faithfully.
