Is this correct?

[Emeka <emekamicro@...>]

Hello All

I stumbled on the above while going through Lua manual... I need your help to here.

     x = string.gsub("4+5 = $return 4+5$", "%$(.-)%$", function (s)
           return loadstring(s)()
         end)

I am of the view that it should be,

     x = string.gsub("4+5 = $return 4+5$", "%$(.+)%$", function (s)
           return loadstring(s)()
         end)

My question is what is "-" in the above pattern?
