Details:

The following Lua script does not work as expected.


weechat.register('test', 'JustAPerson', '0.1', 'MIT', 'Broken C Stack bug',
'', '')
local function func()
        weechat.print('', 'This will cause an error and is never actually 
printed')
end

local thread = coroutine.create(func) -- loads `func` in a separate lua_State
coroutine.resume(thread) -- should be equivalent to `func()`


I have attached a patch specific to weechat_lua_api_print(). A similar
solution will need to be applied to *every* public weechat_lua_api_* function.
