Fix a couple of places that would loop forever if attempts to read a stdio file

set ferror() but never set feof().  This is known to be the case for recent
glibc when trying to read a directory as a file, and might be true for other
platforms/cases too.  Per report from Ed L.  (There is more that we ought to
do about his report, but this is one easily identifiable issue.)
