Line 3 of code listing 1.2 looks like a comment, but it does not begin with a '#' character. This bug appears to affect every language version except Korean.
Fixed for the following languages: en, es, fr, it, nl. Did not fix the following languages: ru, ja. Someone that knows russian and japanese please fix and close this bug.
FWIW, I only speak English and *some* Spanish. I just clicked all the links and noted which versions had a line that didn't start with '#'. I'm assuming you avoided ru and ja because of the charsets, though..
please fix guys
Done in ru George
This seems to be fixed in the latest ja/env.d-howto.xml (rev 1.4). Closing.
