Comment 1 for bug 299685

The following patch allows upgrades from or to color=0 packages.

Quoting Jeff:

01:37:42  jbj_> colored dependencies can only be matched by same color or color 0.
01:38:22  jbj_> 1 == elf32, 2 == elf64
01:39:12  jbj_> 0 <-> 2 should switch fine. 1 <-> 2 is what makes no sense.
