This will strip lone CR at the end of line, in addition to CRLF at
the end of line (which you want to handle) and LF at the end of line
(we always have removed), making it work even on ancient MacOS.
If we really cared, I guess we could write it like this:
if (len && sb.buf[len - 1] == '\n') {
len--;
if (len && sb.buf[len - 1] == '\r')
len--;
sb.buf[len] = '\0';
}
but your version should be fine as-is.
Thanks.
