I have a patch doing this, but there is one problem that i don't see how
to solve neatly. At the moment we set hidden-headers to the union of
message-hidden-headers and notmuch-mua-hidden-headers. This means that
if the user wants to show a header that is normally one of
message-hidden-headers they have to set message-hidden-headers (ie they
can't just change notmuch-mua-hidden headers).

If we want it that people can show such a header just by changing a
notmuch variable then I don't see how to do it neatly without breaking
some existing setups.

Any suggestions?

Best wishes
