clang gives the following warning:
builtin/receive-pack.c:327:35: error: sizeof on array function
parameter will return size of 'unsigned char *' instead of 'unsigned
char [20]' [-Werror,-Wsizeof-array-argument]
git_SHA1_Update(&ctx, out, sizeof(out));
^
builtin/receive-pack.c:292:37: note: declared here
static void hmac_sha1(unsigned char out[20],
^
---
I dislike changing sizeof to a magic constant, but clang informs me that
sizeof is doing the wrong thing. Perhaps there's an appropriate constant
#defined in the code somewhere?
