Sorry for not noticing this before.  The "If unsure, say $X" should
really match the default value.

On the other hand, given that we are hiding all these options behind
CONFIG_EXPERT, I am not sure that we need "If unsure" clauses.  Anyone
who isn't sure shouldn't have turned on CONFIG_EXPERT to start with.
