default stack trace function

[Frederico Rodrigues Abraham <devotion97@...>]

Hi.
I noticed something that seems strange to me when using the error
function with an error level parameter.
Consider the following piece of code:

p3 = function()
  error("the error",3)
end

p2 = function()
  p3()
end

p1 = function()
  p2()
end

luaf = function(d)
  print(d)
  p1()
  return "the result"
end

print(luaf("ha!"))
-- END OF CODE

Running the lua 5 interpreter with this file gives the following stack trace:

lua5: stacktrace.lua:10: the error
stack traceback:
        [C]: in function `error'
        stacktrace.lua:2: in function `p3'
        stacktrace.lua:6: in function `p2'
        stacktrace.lua:10: in function `p1'
        stacktrace.lua:15: in function `luaf'
        stacktrace.lua:19: in main chunk
        [C]: ?

The line where the error happened seems correct. (line 10, the call to
p2() in p1 body)
Shouldn't the stack trace omit the lines for error levels 1 and 2?
(line 2 and 6, respectively)
