Bug#2281: emacs ange-ftp fails from xterm

[Ian Jackson <ijackson@chiark.chu.cam.ac.uk>]

Package: emacs
Version: 19.29-4

If Emacs is invoked from an xterm then ange-ftp doesn't work; the FTP
program's readline interface produces terminal escape sequences
appropriate to TERM=xterm, which it is obviously receiving from Emacs.

Emacs should not set TERM=xterm for its subprocesses (it runs ftp in a
pty, I believe).

Invoking emacs as (bournelike shell)
 TERM=dumb emacs &
works around the problem.

The system has xbase 3.1.2-7 installed, and netstd 1.26-1.

Ian.
