Bug#2114: dselect HD method fails without redundant Packages files

[Richard Kettlewell <richard@uk.geeks.org>]

Package: dpkg
Version: 1.0.8

(Well, that's 1.0.8 according to the package, 1.0.7 according to dpkg
--version.)

I selected the hard disc access method, entered `none' for
distribution top level,

	/home/ftp/pub/debian/debian-1.0/binary

for main binary directory and `none' for everything else.  I then told
dselect to update the list of available packages.  However, the hard
disc access method then tries to read a file called "" for each of the
packages files I refused to supply.

----------------------------------------
Uncompressing /home/ftp/pub/debian/debian-1.0/binary/Packages.gz ... done.
Updating available packages info, using packages-main.
Information about 324 package(s) was updated.
Updating available packages info, using .
dpkg: failed to open package info file `' for reading: No such file or directory

update available list script returned error exit status 1.
Press RETURN to continue.
----------------------------------------

I suggest a patch to /usr/lib/dpkg/methods/disk/update:
