reset sets tty settings while clear doesn't, large enough
difference to probably not make one a OLDTOY pointing at the other.
Although reset does everything clear does
Looking at the man page for reset, it does even more historical stuff that
doesn't matter today, like "-r" which is the same as "reset; echo Terminal type
is ${TERM}."
and "-s" which is "reset; echo TERM=$TERM;"

ncurses clear does seem to have a -x option to save the scrollback buffer.
Not too important but it'd be one line of code to implement ("if
(!toys.optargs) xputsn("\e[3J");")

What is the oldest version of Linux are we planning to support? The nommu stuff
seems to have only
been done on 2.4/2.6 kernels from 15 years ago. So is "\e[3J" (A escape code
added in 3.0)
something we can use?
