Hmm. I kind of agree with this, but at the same time I suspect that no
caller should ever care about the loglevel characters (since they won't be
_shown_), so your change still doesn't make it return a sensible value.

So I get the feeling that you should also add a

message_len -= 3;

to the case where we peel off the "<.>" loglevel part at the head of the
string. No?

Or we could just change it to 'void'. As Joe Perches says, nobody really
cares deeply enough for this to generally even matter.
