Yeah, thanks for the vote of confidence, Josh, but I'm not yet
comfortable enough here to commit anything without running it by
the list first anyway.

You have one, I have one, lukem has one, Paul Fox has one, Oliver
Kiddle has one, Josh wants one, and I bet Jerry Peek has one :).
I think this is filling a definite gap.

Sure, I don't care about the names; maybe just prefix them with
'mh'? It looks like someone was moving in that direction once
upon a time (mhlist, mhshow, ...).

I can write a simple man page, if this is to be included.

I didn't know this was possible. How does that work?
Unseen-Sequence: unseen foo
Does context_find(usequence) return "unseen foo" or what?

I don't know where I got the notion of "unseen" as a default;
maybe from the original 'new', or maybve ex recto. Anyway, I can
make it error out.

Sure, but there is no function like scan(char *folder, char
*msg_spec), and breaking this out of uip/scan.c is a task for
another day (and probably for someone else :) (but see below).

Keeping that file sorted as you prefer is up to you :). My inc
script updates it as it creates new folders, and has a
configurable sort. As another example, Paul Fox says he has a
similar script which keeps a sort order and excludes some folders
and therefore he can't use this, but he could have it store that
order in .folders instead.

Are you sure? All pointers are the same size, regardless of the
size of the data they point to, and there is no type checking on
a variadic function. So, why the cast?

Hmm, I guess it's easy enough to adapt it to take a sequence
argument, or arguments, as it needs to handle multiple unseen

Not quite; 'scan $(cat $(mhpath +)/.folders) unseen' isn't as
nice as just 'unseen'.
For the record: I've never used 'unseen'; I just implemented for
feature parity with the original. Especially if we change the
names, I'm fine with dropping it entirely. This would also
address Peter's concern about system(scan).
