Can't we read namelists from stdin anymore ?

Yes, of course it *should* work (please file a PR, if nothing else).
The problem is that the (by now quite comprehensive!) testsuite only
tests using regular files, so bugs that only affect special files like
terminals, pipes, etc. tend to slip by undetected. Suggestions (or
even better, code!) on how to test special files within dejagnu
welcome. Or if that's not possible, perhaps creating an external
gfortran IO testsuite that can test functionality with special files
(how? when? who?).
