First, I have doubt if it would be better to use this as recommended and
add to the instructions, after second further below.

I need to remember to leave these. Second time I notice you doing it. (I
am also trying to add things to the pages to help development.) Very
good. Thanks.

Second: I noticed this in the previous update I did, thought a little,
tried with and without. I do not remember if I read something about it
or not. Should have asked before.

The point (or the dumb question, forgive me for not knowing much about
this) is: although it is easy to see "whois" is linked to libidn, I
cannot notice any difference with or without. Would you an example,
please? With an example, I would come to first above: being useful,
should it not be recommended?

$ ldd /usr/bin/whois | grep libidn
        libidn.so.11 => /usr/lib/libidn.so.11 (0xb76f1000)

$ scanelf -F "%f: %n" /usr/bin/whois
FILE NEEDED
whois: libidn.so.11,libc.so.6

$ diff whois-google.com-before-idn.log whois-google.com-after-idn.log
