I understand where you're coming from, but I have to ask ... when
people use mhpath to get the path of an MH message, what, exactly,
are they trying to accomplish? Usually it's something along the
lines of "use some Unix text processing tool on this message". For
that you need to download the whole thing. Obviously for something
like "scan" you don't need the whole message (well, depending on
your scan format, you might, or at least some of the beginning of
the message). I think mhpath isn't part of the "normal" flow of
MH, but if it is for people, I'm interested in how you use it (I
use it, but only occasionally, and my usage is such that I'd need
the whole message). So if you want to have mhpath return IMAP URLs,
okay, I'm fine with that. But personally I think that's not as
useful as having mhpath download the whole message.

Well, here's where I think we are regarding that:
- Paul suggested what such an API should look like (specifically, he
said "man 3 db". He said he'd do some work on designing this API
if people thought it would be a good idea.
- My judge of the consensus of the list was that it was a good idea;
okay, there weren't many responses. I (and maybe a few others) said
we thought it was a good idea. No one said they thought it was a
bad idea.
- That's where things stopped. I've been busy, so I didn't want to
bug Paul about it. I suspect Paul's been busy too, and didn't want
to work on it until he had a chunk of time free.
- My gut tells me that even thought there is a danger of the "design by
committee" problem, we should discuss this on nmh-workers. I think there
is enough good ideas here that it would be useful to solicit input
from people. I could be persuaded otherwise.
