[Patch v5 2/3] emacs: convert notmuch-address-harvester to use notmuch-address

[Mark Walters]

Hi

I have looked through and tried patches 1 and 2 and it looks OK to
me. So at least a sort of +1 on them combined (I didn't really look at
them separately as they seem to make more sense as 1 lump).

I agree with Jani about both the date option, and deduplicate
possibility, and we may also want to add an option to use
--output=sender.

However, I think anything like that could come as a later patch. For the
moment the only thing I think we need to consider is the variable
notmuch-address-command. Do we want to have something other than nil to
mean use the elisp completion? In particular we could have something
which can be extended to specify the options above.

Additionally, aesthetically, I like the idea that setting this variable
to nil disables address completion.

Best wishes

Mark
