When you remove the last vi alternative, ae is run by a script in /bin
with the ae2vi.rc file. The current release is broken in this reguard, but
the next one will be fixed to continue to emulate vi.

Although the xterm does set itself up with TERM=xterm, there are any
number of reasons for the TERM variable to be changed (vt100 comes to
mind for various telnet targets), which makes this an unreliable way to
deal with this.
What would be wrong with having the "non-x" ae tell you in the help screen
what you need to run to get xterm support? The need for this xterm support
comes from folks who want to administer a base system remotely from a
system using an xterm. This is a fairly restricted set of folks who should
be "clued" enough to deal with the help message.
Ya think?
