These are the patches I have so far for format string warnings with
-Wnon-const-format, covering the bin/ tree.  Please review (especially
whether I've got all the __printflike/__printf0like attributes correct
-- the difference being whether the function gracefully handles a NULL
format string, like the err() family, or through explicit checks).

More to follow, but I don't want to overwhelm people.

Kris
