patch to enable --help in /hurd/init |

Hello,
Here's a patch to enable --help on /hurd/init. Now users can run
/hurd/init --help and actually get information on what this translator
is supposed to do.
Instead of the user seeing:
$ /hurd/init --help
/hurd/init: can only be run by bootstrap filesystem
The user now sees:
$ /hurd/init --help
Usage: init [OPTION...]
Start and maintain hurd core servers and system run state
-d, --debug
-f, --fake-boot This hurd hasn't been booted on the raw machine
-H, --crash-debug On system crash, go to kernel debugger
-n, --init-name
-q, --query Ask for the names of servers to start
-s, --single-user Startup system in single-user mode
-?, --help Give this help list
--usage Give a short usage message
-V, --version Print program version
Report bugs to <bug-hurd@gnu.org>.
Please commit the attached patch!
Ben
* init.c (main): Only pass ARGP_NO_ERRS to argp_parse when invoked by
the bootstrap filesystem.
(flags): New variable.
