+ to separate the multiple same nicknames from each other. The format
+ types are defined below and they can appear in any order in the format
+ string. If this is NULL then default format is used which is the
+ default nickname without anything else. The string MUST be NULL
+ terminated.
+
+ Following format types are available:
+
+ %n nickname - the real nickname returned by the server (mandatory)
+ %h hostname - the stripped hostname of the client
+ %H full hostname - the full hostname of the client
+ %s server name - the server name the client is connected
+ %S full server - the full server name the client is connected
+ %a number - ascending number in case there are several
+ same nicknames (fe. nick@host and nick@host2)
+
+ Example format strings: "%n@%h%a" (fe. nick@host, nick@host2)
+ "%a!%n@%s" (fe. nick@server, 2!nick@server)
+ "%n@%H" (fe. nick@host.domain.com)
+
+ By default this format is employed to the nicknames by the libary
+ only when there appears multiple same nicknames. If the library has
+ only one nickname cached the nickname is saved as is and without the
+ defined format. If you want always to save the nickname in the defined
+ format set the boolean field `nickname_force_format' to value TRUE.
