* The idea is as follows:
|
|
* In most messages (for protocol 10+) the original nick will be
|
|
* replaced by a 3 character string: YXX
|
|
* Where 'Y' represents the server, and 'XX' the nick on that server.
|
|
*
|
|
* 'YXX' should not interfer with the input parser, and therefore is
|
|
* not allowed to contain spaces or a ':'.
|
|
* Also, 'Y' can't start with a '+' because of m_server().
|
|
*
|
|
* We keep the characters printable for debugging reasons too.
|
|
*
|
|
* The 'XX' value can be larger then the maximum number of clients
|
|
* per server, we use a mask (struct Server::nn_mask) to get the real
|
|
* client numeric. The overhead is used to have some redundancy so
|
|
* just-disconnected-client aren't confused with just-connected ones.
