Subject: [PATCH] emacs: notmuch-fontify-headers: Remove unneeded progn and
 indent correctly.

The defun special form doesn't require a progn. And the remainder
of the function was previously indented in a misleading way, (as
if each "if" was always evaluated, rather than each only being
evaluated if all the previous evaluated to nil).
