AgentManager.cs Chat function does not allow zero-length messages to be sent

[stonejohnson]

AgentManager.cs Chat function does not allow zero-length messages to be sent, which breaks some RLV functionality in Radegast. It would be great to be able to send zero-length messages.

On line 1603 of AgentManager.cs there is the line

        else if ((message.Length > 0) && (message.Length < 1000))

which kills zero-byte-length messages. Maybe this is necessary for other stuff to work, but it kills these RLV functions when you get to the bottom of the folder tree - it's important to return a null message (and not a blank which is interpreted as a filename). Changing the line to

        else if ((message.Length >= 0) && (message.Length < 1000))

will fix the problem. Alternately there could be an alternate call that would allow the zero-length message, e.g.,

ChatZ(string message, int channel, ChatType type, bool split, bool hidechunk) same functionality but allows the zero-length message.

Note that this aspect of RLV used to work in Radegast (5 years ago?) so it was permitted to send the zero-length message.
