Yes. A fine idea.

A quick grep through some of my recent mails does show precedent for
this kind of thing:

  User-Agent: Gnus/5.110011 (No Gnus v0.11) Emacs/23.1.90 (gnu/linux)

Unsurprisingly, these suer-agent strings can become arbitrarily
unwieldy:

  User-Agent: Mozilla/5.0 (Windows; U; Windows NT 5.1; de; rv:1.9.1.9) Gecko/20100317 Lightning/1.0pre Thunderbird/3.0.4

Or extremely simple:

  User-Agent: Sup/0.11

I don't see the advantage of duplicating the name and version in the
parenthesized comment, but here's an idea that looks useful:

  User-Agent: Loom/3.14 (http://gmane.org/)

So I propose something like:

  User-Agent: Notmuch/0.2 (http://notmuchmail.org) Emacs/23.1.1 (gnu/linux)

If anybody wants to start assembling a patch to generate that, that
would be great.
