regarding that stack of newline chars expressed at boot

This is from the "better late than never" file. So yes, any machine I
had with a serial console was kicking out a newline char on every one
of the "autoboot_delay" countdown. Seems to be a default of 10 secs
and so therefore I was seeing ten lines of stuff.

Seems to be related to :

The trivial solution is to NOT use and old fashioned 80x24 DEC VT100
type XTerm size for the session that connects to serial. The behavior
vanishes at 80x25 now. I see that as the old DOS PC-Term size that some
folks at Microsoft loved. Many years ago.

Maybe it would be more elegant to just output the countdown secs number
and then utter 010 BS chars and keep kicking out numbers that overwrite
whatever was there before?

Or do nothing.

Hardly an issue really. Just seemed weird when I saw it.

Thanks for letting  me paint the bikeshed.
