[PATCH] notmuch new: add a --in-directory option

[Austin Clements]

I haven't thought about this as a patch yet, but wanted to point out
that it should probably skip the removal step if it's only scanning a
subdirectory.  Otherwise, messages that are moved out of the scanned
directory into some other may be considered deleted and get removed
from the database.

That aside, I'm curious what the use case for this is.
