/bin/sh is what? Can I set tab autocompletion for that sh?

Wow, this really works (on more recent versions of FreeBSD)!
I would never have associated this with emacs-style line editing.
Still the manual doesn't seem to mention tab completition;
however, the manual for editrc seems to at least _suggest_
that kind of functionality in two entries (one vi-, one em-),
even though it is not explicitely mentioned.

Enabling this particular feature makes /bin/sh more usable in
"worst case scenario" interactive shell sessions. ;-)
