That is the point! Show is in each other's head. Some would consider single
LF as one empty line, others as two, and some as a broken file.

It does not work under Windows. As you said about VMS, why should I care
what a non-existent hobbyist's OS does? (:-))

I don't use UNIX, remember. Our log files are binary. (Trace files are
texts.)

Yes, you stream graphical minutes, as you said...

IDE is a front end to a text editor. You still need a text to print, store,
pass to the compiler.

Any. You cannot rely on the remote host always sending you graceful
disconnect. Many devices we are dealing with don't even have such thing.
They just become silent.

As a practical example, load some large text page into the browser. Before
it completes, in the middle, pull the Etherenet jack out. Observe the
stream end!
