[Wrath Classic 3.4.3] Chat macros throw "attempt to concatenate a nil value" error

[SDPhantom]

Try to run a macro with /s test as an example.

Message: Interface/FrameXML/ChatFrame.lua:4524: attempt to concatenate a nil value Stack: Interface/FrameXML/ChatFrame.lua:4524: attempt to concatenate a nil value [string "@Interface/FrameXML/ChatFrame.lua"]:4524: in function 'ChatEdit_UpdateHeader' [string "@Interface/FrameXML/ChatFrame.lua"]:4883: in function <Interface/FrameXML/ChatFrame.lua:4845>

This happens because ChatEdit_UpdateHeader() is called on the internal EditBox that's used by the macro system to execute commands. This EditBox has no name, so an error is thrown when trying to access the EditBox header (also doesn't exist) through _G[editBox:GetName().."Header"].

This is fixed in the PTR build that's just gone up.
