I was looking at what Bash and tnftp do when they run in an Emacs
comint-mode (shell and ange-ftp, respectively) and the below seems to be
the easiest fix. It's more or less directly copied from tnftp.

diff --git a/ftp/main.c b/ftp/main.c

   else
     usereadline = 0;

Let me know if you think this is an acceptable fix.
