I've forgotten whether this issue was ever resolved: what should happen if the
output stream is a VMS record-oriented file?  If the currently buffered output
contains no newlines, is it appropriate for fflush() to do nothing, and return
success?

(The problem is that, if I'm not mistaken, a `line' in such a file consists of
a record with a byte-count prefix, and no actual newline character.)
