Bug#678091: python-apt: recommends xz-lzma but does not use it

[Jonathan Nieder <jrnieder@gmail.com>]

Package: python-apt
Version: 0.8.4
Severity: minor
Justification: http://bugs.debian.org/677991
Tags: patch

Hi,

Since December, 2011 (due to [*], presumably), python-apt recommends
xz-lzma to ensure apt's ExtractTar is capable of installing
lzma-compressed packages (like google-chrome).  Now in sid the xz-lzma
package is being removed in favor of xz-utils providing "lzma" through
the alternatives system directly, making that recommends harder to
literally satisfy.

Sorry I missed this before uploading.  We can add a Provides to
xz-utils if appropriate, but it seems that python-apt has not used the
"lzma" command in practice since apt 0.90.

  * apt-pkg/aptconfiguration.cc:
    - if present, prefer xz binary over lzma

How about something like this patch?

Thanks,
Jonathan
