That will not be portable. Not all builds are gcc. Since this is in a
non-hot area, we simply should scan backwards with a char pointer, and set
it when we find it. Or simply keep the length, or scan forward. Or we
could memset the buffer, make it large enough (17 chars at least), then
simply scan from tail, and know when we get to the 80, that we are chopping
off the right one.
