Usually, big transfers are split > up into smaller fragments, say 128-256 byte. So, for readability, I'd > still favour %*ph. I was thinking that limited the size of the output field to 64 bytes. But reading vsprintf.c again, it appears it's actually the size of the binary blob that it's converting to hex that's limited to 64 bytes. I would prefer shorter lines - 128 bytes of hex still isn't entirely readable, even with separators interpolated, but I'll add this.
