these little comments don't add much, it's clear from the check what you're
checking. however, a more general comment here might be helpful.

could you have a method like "ContainsAll" and overload that with a 2 and 3
version? because

Contains(a, b) && Contains(a, c)

is equivalent to Contains(a, b, c), right? and the latter looks much nicer.

epic nit: can we have these in alphabetic ordering (a) in those Contains calls
and (b) when choosing an arbitrary message ID.

what about read+copy+delete?

[mhm, 2014/07/07 23:58:32]

The original logic didn't say anything about this case. It was written such that
if read+copy exists it doesn't care about delete. However, I changed that now
and added a new string for it.
