Hi David,

Thanks for the review. A couple of comments inline:

This is the cause of the spurious blank line, but without it the tests
complain about missing a blank line at the end of the file.  There may
be a better way to deal with this - I'll experiment.

I like this being generated in the MUA because then it can be
customized easily (e.g. in my later patch).  Of course, it would also
be possible to add this as a config option for the CLI and generate it
there, but it feels to me like if there's a line between notmuch and
the MUA, this belongs on the MUA side, especially in MUAs that are
formatting the reply themselves anyway.

I'm happy to hear more discussion on this, and will implement whatever
seems best.  I don't actually use the customization myself, it just
strikes me as a useful feature.
