[bug #31736] grep chokes on filenames starting "--" (minus-minus)

[Eric Blake]

Update of bug #31736 (project grep):

                  Status:                    None => Invalid                
             Open/Closed:                    Open => Closed

Follow-up Comment #1:

Not a bug.

Use 'grep -- --file' or 'grep -- ./--file' instead.

The behavior of -- to end option arguments is mandated by POSIX.

Additionally, when running with POSIXLY_CORRECT set in the environment, you
are guaranteed that 'grep str --file' will treat --file as a filename per
POSIX (since str is not an option); but when not running with POSIXLY_CORRECT,
you are subject to the GNU behavior of option reordering (--file is recognized
as an option even though str is not); the same approach of using 'grep -- str
--file' also works to avoid this option reordering.
