struct diff_filespec defines mode to be an 'unsigned short'. Several other places in the API which we'd like to interact with using a diff_filespec used a plain unsigned (or unsigned int). This caused problems when taking addresses, so switch to unsigned short. Signed-off-by: Elijah Newren <newren@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
