Bug#679374: devscripts: [rc-alert] please exit on unknown option

[George Danchev]

Package: devscripts
Version: 2.11.9
Severity: minor

Dear Devscripts Maintainers,

In a offline session I typoed rc-alert --hepl,
whereupon wget call attempt kicked in:

Unknown option: hepl
rc-alert: wget failed!

(in a online session) followed by excessive bug list, instead
of just barfing at me and/or showing me the help blurb:

diff --git a/scripts/rc-alert.pl b/scripts/rc-alert.pl
index 610cc65..63c099e 100755

-	   );
+	   ) or exit 1;
 
 if ($opt_help) { print $usage; exit 0; }
 if ($opt_version) { print $version; exit 0; }



Or even more lazy:
-	   );

so the reader won't get a chance to re-type and typ0 it
once again, but just the help :P
