bug#29617: `seq 1 --help' doesn't give help

[chadweisman]

Hello,

I am using coreutils version 8.27 on Fedora, and I don't see this fixed in 
8.28's NEWS.

$ seq 1 --help
seq: invalid floating point argument: ‘--help’
Try 'seq --help' for more information.

We should be able to put the options anywhere and not necessarily before any 
arguments.  And even if not (e.g. POSIX conformance overrides,) --help should 
be handled specially to conform to the GNU coding standards. [1]

cheers,

Chad.
