It appears that the RHEL default /etc/initrc file defines a bunch of escape
sequences "for linux console and RH/Debian xterm" cursor keys when in emacs
mode.

Our servers are RHEL, my ssh client emulates xterm, and is in the default
emacs mode.  Thus, the cursor keys automagically work for me, and I just
learned that I've been in emacs mode this whole time!
