[M3devel] bug in Fmt.F

[mika at async.caltech.edu]

Ah, sorry, my choice of words was imprecise.  By "does not terminate" I do
indeed mean that it raises the exception.  I should have written "does
not terminate normally, raises an exception"

(My runtime turns the uncaught exception into abort, that is,
non-termination of the F procedure.)
