The reporter specifically mentioned busybox command line editing.
We cannot expect embedded systems to rely on termcap/terminfo.
Rather they will issue hardcoded VT100 escape sequences - like
ESC [ J, and expect the terminal emulator to DTRT...
I've tested the 'echo' example with both xterm and minicom (which I
use with embedded systems). Both behave identically - for ESC [ J
and for ESC [ 1 J -- and in accordance with the reporter's expectations
for a "true" VT100 terminal.
So you may claim that the behaviour is "undefined" - but practical
tests shows "consistent" behaviour, different from what Emacs term
does.
IMO, we should fix term to behave like other VT100 emulators.
The current behaviour is clearly broken -- besides, fixing this
doesn't change the semantics of the only case where it was defined
before.
