+ * There are two ways to call this method, either with one potential list or with two potential lists.
+ * We need to handle two potential lists for JOIN, because a JOIN may contain two lists of items at once:
+ * the channel names and their keys as follows:
+ *
+ * JOIN \#chan1,\#chan2,\#chan3 key1,,key3
+ *
+ * Therefore, we need to deal with both lists concurrently. If there are two lists then the method reads
+ * them both together until the first runs out of tokens.
+ * With one list it is much simpler, and is used in NAMES, WHOIS, PRIVMSG etc.
+ *
+ * If there is only one list and there are duplicates in it, then the command handler is only called for
+ * unique items. Entries are compared using "irc comparision" (see irc::string).
+ * If the usemax parameter is true (the default) the function only parses until it reaches
+ * ServerInstance->Config->MaxTargets number of targets, to stop abuse via spam.
+ *
+ * The OnPostCommand hook is executed for each item after it has been processed by the handler, with the
+ * original line parameter being empty (to indicate that the command in that form was created by this function).
+ * This only applies if the user executing the command is local.
+ *
+ * If there are two lists and the second list runs out of tokens before the first list then parameters[extra]
+ * will be an EMPTY string when Handle() is called for the remaining tokens in the first list, even if it is
+ * in the middle of parameters[]! Moreover, empty tokens in the second list are allowed, and those will also
+ * result in the appropiate entry being empty in parameters[].
+ * This is different than what command handlers usually expect; the command parser only allows an empty param
+ * as the last item in the vector.
+ *
+ * @param user The user who sent the command
+ * @param handler The command handler to call for each parameter in the list
+ * @param parameters Parameter list as a vector of strings
+ * @param splithere The first parameter index to split as a comma seperated list
+ * @param extra The second parameter index to split as a comma seperated list, or -1 (the default) if there is only one list
+ * @param usemax True to limit the command to MaxTargets targets (default), or false to process all tokens
+ * @return This function returns true when it identified a list in the given parameter and finished calling the
+ * command handler for each entry on the list. When this occurs, the caller should return without doing anything,
+ * otherwise it should continue into its main section of code.
