Ah... I think I know what's going on.
The leftover data in the strbuf is normally (when there is no errors) an
unterminated line. So instead of doing:
- fprintf(stderr, "%s: protocol error: no band designator\n", me);
+ strbuf_addf(&outbuf,
+ "\n%s: protocol error: no band designator\n",
+ me);
you could omit the final \n in the format string and:
- if (outbuf.len > 0)
- fprintf(stderr, "%.*s", (int)outbuf.len, outbuf.buf);
+ if (outbuf.len)
+ fwrite(outbuf.buf, 1, outbuf.len, stderr);
strbuf_release(&outbuf);
and here a \n could be added before writing out the buffer.
