[Evolution-hackers] mail display/format code, multipart/related

[Not Zed <notzed ximian com>]

Dan/Jeff,

The mail format code for related parts can match other related parts
which are not part of the same hierarchy, and other parts which are
sub-parts of say a multipart/mixed (i think), or other parallel parts. 
RFC2557 8.2(d) seems to suggest it should only reference parts in the
same multipart/alterntive, or an enclosing multipart/alternative, etc.

Was this done for a specific reason, or just implementation simplicity.
