This patch (or at least the idea of it) suppresses these warnings when
the file hasn't been created yet, and forces the index to be created
when it's not there. The pervasion of current warnings can arise
AFAICS from a zero length mailbox being checked repeatedly but because
there are no new messages it repeatedly isn't created, gobbling /var,
and agitating me.

(Maybe could have a LOG_{INFO,DEBUG} to say it's not there but scheduled
for creation.)

Paul, has a mild fetish about reducing >= LOG_WARNING
