From 92912abb162c809019c1c1d0f16c01be2d8be533 Mon Sep 17 00:00:00 2001

Subject: Make the 'searchheaders' option behave how it was supposed to. If
 enabled, the string '/to:y' will match strings in the To, Cc, and Bcc header
 fields. Whereas, '/To:y' will match only the To field. Edit the manpage and a
 code comment to indicate the correct behavior.
