...except that it is. The default /root/.shrc contains
if [ -f /etc/shrc ]; then
and /etc/shrc sets both -o emacs and -o tabcomplete.
The issue appears to be that (1) because su doesn't start a login
shell by default, it doesn't read /root/.profile, but a console root
login does, leading to differing behavior, (2) you need set -o emacs
as well as set -o tabcomplete for it to do anything, (3) several of my
machines were installed long enough ago that they don't have /etc/shrc
in place, and (4) when I checked /root/.profile and /root/.shrc point
#3 caused me to not look at the /etc/shrc on the newly installed
machines so I didn't see the set -o instances.

Yes; it runs it both in and out of a subshell to avoid visible error
messages in ksh.
