Yes, I think init(8) should attempt to pass a suitable TERM to the
single-user shell. This value could be hard-coded (TERM=xterm will
usually be close enough) or taken from /etc/ttys somehow.

The sh(1) patch to allow updating libedit's TERM looks OK, although it
probably should not react to TERM changes in subshells.

I do not plan to revert r206182, putting 'set -o emacs' in root's shell
startup files instead. I did 'set -o emacs' in the shell itself so that
it works even if there are no startup files at all, such as 'make
buildenv' and chroot shells.
