Includes/Excludes within <unpackOptions> are ignored

I have the following snippet in my assembly descriptor which does not work:

-snip-
<moduleSet>
<includes>
<include>my:module</include>
</includes>
<binaries>
<unpack>true</unpack>
<unpackOptions>
<excludes>
<exclude>META-INF/**</exclude>
<exclude>**/.do_not_remove</exclude>
</excludes>
</unpackOptions>
<outputFileNameMapping/>
<outputDirectory>/</outputDirectory>
<fileMode>644</fileMode>
<directoryMode>755</directoryMode>
</binaries>
</moduleSet>
-snip-

Debug output shows:

-snip-
[DEBUG] includes:
*/

[DEBUG] excludes:
none
-snip-

I believe the problem is at line 271/272 of ModuleSetAssemblyPhase (in the 2.2-beta-2 revision, anyway) – it calls "task.setUnpack( binaries.isUnpack() );" but does not set the unpack options (if present), hence they are ignored

Patch is attached, and works just fine in my case above.
