Subject: [PATCH 2/4] diffcore_filespec: add is_binary

From: Junio C Hamano <[email-masked]>
Date: Thu, 28 Jun 2007 23:35:59 -0700

diffcore-break and diffcore-rename would want to behave slightly
differently depending on the binary-ness of the data, so add one
bit to the filespec, as the structure is now passed down to
diffcore_count_changes() function.
