But it's not necessarily clear that you've reached the end of a thread,
which means it's somewhat indeterministic if the "inbox" tag is removed
or not.  If users have to explicitly remove all tags other than
"unread", then this gets rid of this problem all together.

I actually submitted this patch because there was noise on #notmuch
about people (including from cworth) not liking the default behavior
where the "inbox" tag is removed by the advance function.

I would like to push it back the other way.  Having specific tags
modified by specific commands is something particular to individual
users.  If a user wants to do something special, they can make their own
function to do that.

jamie.
