[PATCH 06/11] search: avoid needless decode

[Eric Wong <e@80x24.org>]

Email::MIME should handle everything for us and make things
work nicely with Xapian (assuming I understand how encoding
works in Perl).

While we're at it, reduce temporary strings and arrays by
using destructive operations and clobbering parts as we
iterate through them.
