According to RFC 2812, the maximum nickname length is 9, but this is actually determined by the server.

In IRCSock.cpp, "m_uMaxNickLen = 9;" should be configurable.

You forgot the "Why?". ZNC reads the NICKLEN from 005 (ISUPPORT). Thus, that hardcoded 9 only matters while trying to establish a connection and there it seems to be only used in SendAltNick(). This function is used to find a new nick when we get a "nickname already in use" reply while connecting.

I can live fine with nicknames being truncated in this one corner case...
