{ "auth", 'a', "AUTH", OPTION_ARG_OPTIONAL,
"use AUTH for authentication",
GRID+1 },What's the point of this? Go figure, probobly a mistake when things got argpified. -a should/must default to "default", and --auth=donkey should use donkey. I believe the patch below should be applied. It will solve the crash. Thoughts? Go for it.
