description:
There is no standard way of getting a list of aliases for the
terminal. However, some applications such as telnet want to know this.
ncurses dumps the terminfo header into an undefined variable ttytype
and these applications then parse it to work out the aliases.
We should do the same for now, until a standard mechanism for getting
the information is available or the need for it goes away.
