Re: GNU sed maintainers, please document GNU sed's "-E" option (which is now in POSIX)

[Jose E. Marchesi]

Hi David.

Thank you for submitting the patch.  Given that -E has been added to
POSIX I see nothing wrong on documenting -E along with -r.

Could you please provide a ChangeLog entry documenting the changes?

Also,

    +usually have less backslashes.

Please replace `less backslashes' with `fewer backslashes' as Bruce
suggested.

    -   /* Undocumented, for compatibility with BSD sed.  */
    +   /* "-E" is in POSIX, http://austingroupbugs.net/view.php?id=528 */
        case 'E':
        case 'r':
          if (extended_regexp_flags)

That comment about -E being in POSIX is unnecessary.  Just remove the
comment claiming that -E is not documented.

Would you like to update your patch and resend it using git
format-patch?

Thanks :)
