Since this structure handles an array of object IDs, rename it to struct oid_array. Also rename the accessor functions and the initialization constant. This commit was produced mechanically by providing non-Documentation files to the following Perl one-liners: perl -pi -E 's/struct sha1_array/struct oid_array/g' perl -pi -E 's/\bsha1_array_/oid_array_/g' perl -pi -E 's/SHA1_ARRAY_INIT/OID_ARRAY_INIT/g' Signed-off-by: brian m. carlson <sandals@crustytoothpaste.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>
