+The fact that it's called "stream-LF" (as distinct from "stream-CR" or just
+"stream") suggests that the newlines which terminate the records have some
+significance to the OS.  Is it legal, for example, to write 70000 characters
+without a newline?  If not, this doesn't seem like an acceptable format for
+binary mode.

In VMS it is legal (VMS 4.4 C 2.2).  There are a few system utilities that will
gronk and die when you try to use this format.  I think that this is a small
problem with i/o quotas not being set up correctly, but never did look into
it more deeply.  I got around the problem by not having to use that particular
system utility :-)
