+      header: an object that supports string-to-string hashtable-style access
+              to the raw headers for the message. E.g., header["From"],
+              header["To"], etc.
+  from_email: the email part of the From: line, or nil if empty
+Return value:
+  A string (multi-line ok) containing the text of the signature, or nil to
+  use the default signature.
