Comment (by jreed):

 So do you want to check for : (in the case) instead or get rid of the
 colon (in the getopt)?

 Do we want it to complain about the unknown option or not (in addition to
 giving the usage statement)?

 Note that the src/bin/dhcp6/main.cc uses the colon and checks for the
 colon, but doesn't yet have any switches that have an option argument.

 The colon magic, in my opinion, is not good as it also loses the
 explanation specific to the problem, such as b10-auth: option requires an
 argument -- u
