"apt show" reports misleading conflicts

Packages are reported to conflict with themselves when they actually conflict with a different architecture version of themselves.

For example (and as illustrated below using "apt show" and "apt-cache depends") musepack-tools is reported to conflict with musepack-tools (according to "apt show") but in reality (as revealed by "apt-cache depends") conflicts with musepack-tools:i386.

That is misleading and concerning when read for the first time by probably anyone and apparently a known issue:

http://askubuntu.com/questions/106203/why-do-some-packages-conflict-with-themselves

I consider it a bug and file so accordingly. "apt show", should not mislead as it does, but show at least the same output as "apt-cache depends" does here.

Example runs:

$ apt show musepack-tools

Description: MusePack commandline utilities
 Musepack is an audio compression format with a strong emphasis on high quality.
 It's not lossless, but it is designed for transparency, so that you won't be
 able to hear differences between the original wave file and the much smaller
 MPC file.

 It is based on the MPEG-1 Layer-2 / MP2 algorithms, but since 1997 it has
 rapidly developed and vastly improved and is now at an advanced stage in which
 it contains heavily optimized and patentless code.

 This package contains various commandline utilities for MusePack files:
 * mpcenc (encoder)
 * mpcdec (decoder)
 * mpccut (cut MPC files without reencoding)
 * mpcgain (gain calculation)
 * mpc2sv8 (conversion to MusePack SV8 from older SV)
