LGTM.  One minor nit below, but feel free to ignore it.

Quoth Jani Nikula on Dec 03 at 10:56 pm:
> Use the notmuch argument parser to handle arguments in "notmuch
> new". As a side effect, this fixes broken STRNCMP_LITERAL usage that
> accepts, for example, --verbosefoo for --verbose.

Not that the single character arguments matter right now, but '-n' is
often used for "dry-run", which could actually apply to notmuch new.
