I think that's useful. One can use the interactive dialog to query about the
correct format (as before), if one enters the correct nml one returns without
error (as before), but if one enters an invalid namelist one returns (as
before) but with an error status (new) and without an warning ("namelist read:
misplaced = sign") [new]. (One can use iomsg to get the error string.) And
without err=/iostat=, one gets a run-time error as before.

[Admittedly, I have never used the ? / =? feature thus I might overlook a
useful application which won't work with the new patch, but it seems as if most
things continue to work.]

Thus, I think the patch is fine. As it is not test-suite testable, no test case
is needed. From my side the patch is OK for committal.
