Title:
  apt: incorrect handling of Filename field with spaces

Status in “apt” package in Ubuntu:
  New
Status in “apt” package in Debian:
  Unknown

Bug description:
  Separated from bug #1086997.

  The original report involves a repository where some path names contain spaces.  These end up in the Packages file like:
  > Filename: foo/bar baz/file.deb

  APT considers the entire line after “Filename: ” to be a single
  filename value, and issues a HTTP request for the same (note: with a
  malformed request line, see the other bug).

  Packages is a debian control file, subject to debian-policy:
  - no filename /value/ may contain a space [Section 5.1]; and
  - a Filename field contains multiple values, separated by a space [Appendix D];
  so APT has incorrectly read this line as a single filename—“foo/bar baz/file.deb”—when it is actually two: “foo/bar” and “baz/file.deb”.

  In this particular case, the repository in question is not technically
  supported due to the filenames containing spaces (currently prohibited
  in control files).  However, APT should still read this field
  correctly.  Apparently no one is using the multiple-values-in-Filename
  support, so an alternative is to adjust debian-policy.

  Package: apt
  Version: 0.9.7.6
