reboot reboots system when -h is passed

[Jeff Lane ]

-h is a fairly common shortcut for --help.

reboot, however, reboots the machine when one issues the command:

reboot -h

Now looking at the man page, there is an entry for --halt and --help, but NOTHING for -h at all.

reboot should return the same as --help when -h is passed, or at the very least it should error out and not reboot the system, instead perhaps dumping a message like "-h unknown argument".

Also, yes, I get that this is a nit-pick and that there's a history there, this is more a wishlist thing because it's a usability issue.
