 ...except that it is. The default /root/.shrc contains
 
 if [ -f /etc/shrc ]; then
         . /etc/shrc
 fi
 
 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.
