patch: notmuch-mua.el -- message-hidden-headers

[Tomi Ollila]

notmuch-mua.el fails to byte-compile on emacs 22.2.1

The reason is bug in function notmuch-mua-add-more-hidden-headers;
on emacs 23.x it compiles ok, but works incorrectly: The check
which check whether the header is there already always returns nil.
Examples:

(setq foo (list "x" "foo" "bar"))

(member "foo" 'foo)

returns nil,

(member "foo" foo)

returns list ("foo" bar"), as expected.

the former on emacs 22.2.1; backtrace buffer appears with content:

Debugger entered--Lisp error: (wrong-type-argument listp foo)
  member("foo" foo)
  eval((member "foo" (quote foo)))
  eval-last-sexp-1(nil)
  eval-last-sexp(nil)
  call-interactively(eval-last-sexp)

patch to fix this:
