If we take the command line option approach, then the frontend can
request the headers, and have it configured in one location
(setting notmuch-message-headers in emacs affects how emacs mua
calls notmuch-show)...

Also, different frontends may have different usable headers, for
example `X-Face:` probably only works w/ emacs mua =D
