The goal of this patch is to make the check-git-log and checkpatches scripts more
consistent, while maintaining backward compatibility.
I think the range value here should remain unchanged, so users can use the script
as they have been using it before this patch, passing range as $1.

Does the getopts need to be called if $1 is -N? 
I am not sure handling this in the "?" case below would work - as far as I 
know if the N value is more than one character, it would be treated as 
multiple separate characters (e.g. -123 would be treated as -1 2 3)

The -r option is added here to standardise the scripts - this is currently being
used in the checkpatches getops.
