* [PATCH] long-options: add parse_gnu_standard_options_only
gnulib patch!
For the gnulib patch, I believe the following is needed:
====
diff --git a/lib/long-options.c b/lib/long-options.c
index 52ef1f2f8..9567d5135 100644

Otherwise many things fail like so:
$ ./src/dd
./src/dd: unrecognized operand ‘./src/dd’
Try './src/dd --help' for more information.
The "1" value matches the instructions in the getopt_long(3) man page.
* [PATCH] all: detect --help and --version more consistently [FIXME]
FIXME: NEWS, syntax-check, tests.
With the above 'optind=1' change, there are only two major differences:
---
$ nohup-8.30 -/ ; echo $?
nohup: invalid option -- '/'
Try 'nohup --help' for more information.
125
$ ./src/nohup -/ ; echo $?
src/nohup: invalid option -- '/'
Try 'src/nohup --help' for more information.

$ dd-8.30 -- if=/dev/null

$ ./src/dd -- if=/dev/null
./src/dd: unrecognized operand ‘--’
Try './src/dd --help' for more information.
---
Which in turn cause "tests/misc/invalid-opt",
"tests/misc/usage_vs_getopt", and "tests/dd/misc" to fail.
All other test pass as before (tested only on Debian Stretch).

P.S.
https://bugs.gnu.org/29617 "seq: `seq 1 --help' doesn't give help"
will also likely be fixed by your patch.
