coccinelle: convert hashcpy() with null_sha1 to hashclr()
hashcpy with null_sha1 as the source is equivalent to hashclr. In addition to being simpler, using hashclr may give the compiler a chance to optimize better. Convert instances of hashcpy with the source argument of null_sha1 to hashclr. This transformation was implemented using the following semantic patch: @@ expression E1; @@ -hashcpy(E1, null_sha1); +hashclr(E1); Signed-off-by: brian m. carlson <sandals@crustytoothpaste.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>
