Additionally, I see that the ‘.overview’ file for ~/Mail/inbox is
truncated, and only includes entries for the last dozen-or-so messages.
I've tried to regenerate this file with entries for all the messages
without success.  When I do ‘/ o’ now, it shows the items in that file
first, whatever number I enter to the prompt.  The second time I hit ‘/
o’ and enter some number, that many messages are shown.
