That's a correct explanation of the problem. But meanwhile, I don't have
any good justification for that code.

I wrote it originally because I was trying to create an indexer that
would be term-for-term compatible with the indexer of sup. But since
that's not a goal of notmuch, we could easily drop this code.

Does anybody see a reason not to do that?

We don't currently have a way to do that, but I think it could be mighty
handy if we did. It's conceivable that the notmuch indexer could be
augmented to store special terms for beginning-of-line and end-of-line
and then we could make the query parser understand '^' and '$' as
mapping to these terms.

That will be easier to consider after we have a custom query parser,
which is something on my TODO list.
