Pidgin answers CTCP ping and version
Pidgin responds to PING and VERSION (with "Purple IRC"). Beware when testing that: Pidgin itself seems to be buggy when it comes to sending CTCP requests, so better use another client.

At the monthly meeting, we decided we don't care much about PING (mostly harmless, and can be deduced in other ways) and VERSION (there are probably other weirdness in
how the protocol is implemented, that disclose as much).
If anyone feels like it, the next step is to have an option implemented upstream, that allows one to hide this information (verifying that not replying to VERSION actually leaks less than replying
Purple IRC first is left as an exercise to the reader).

Testing today, I got no response to PING, only to VERSION.
That's because our manual test suite doc is buggy: it advises to use https://webchat.oftc.net/ to send CTCP PING, that it apparently doesn't support correctly, so it's no surprise that it gets no answer; going to fix that right now. Using Konversation to send a CTCP PING command shows that Tails 1.2.3's Pidgin does reply to it.
