A better explanation is that the change takes advantage of the abstraction provided by hashcpy() rather than hardcoding knowledge about a particular hash representation. > Leave ppc/sha1.c alone, as it is an isolated component. > Pull cache.h(actually ../cache.h) in just for one memcpy > there is not proper. Strange one-space indentation on all lines of commit message.
