Subject: 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);
