Bug#271978: netinst, wep key with spaces w/ patch

[Chad MILLER <chadmill@gmail.com>]

Package: debian-installer

(adding to BTS so it doesn't get dropped.)

I recently installed on a friend's network, which had a WEP key with a
space in it.  The installer worked, but it wrote a
/etc/network/interfaces file that didn't work.  After boot, the key was
set to the substring up to and not including the space in the WEP key.

I _think_ that a backslash before the space solved the problem, but I'm
not certain.

I don't know if there's a more general problem to be solved or whether
the patch below even compiles.  It's a proof of concept patch, more than
anything else.

Nice work, BTW.  The installer is beautiful.

                                                - chad

Pardon the unsigned e-mail -- I was installing because of a disc crash,
and I haven't fully restored yet.
