Thanks.

Hmph, Peff's quick-fix passed the original "CoNfIg" in &buf directly
to probe_utf8_pathname_composition() without changing its signature.
What is the reason behind these two changes? i.e. why is it
inappropriate to use "CoNfIg" (and append the auml to it to use for
the checking) and why does the function need to take pointer + len,
only to store it in another strbuf itself?
