Shouldn't Digest.result_str call output_bytes instead of repeating the code ?

[Mr-Dispatch]

rust-crypto/src/digest.rs

Line 77 in cc1a5fd

let mut buf: Vec<u8> = repeat(0).take((self.output_bits()+7)/8).collect();

Sorry if it is too nit-picky, I just used the rust-analyzer "Go to Definition" and noticed.
