Breakpoint on function stops at $(QuoteNode(f))

[fredrikekre]

Same test case as in #351:

julia> using Debugger

julia> function g()
           io = IOBuffer()
           return io
       end
g (generic function with 1 method)

julia> function f()
           x = g()
           println(x, "hello")
       end
f (generic function with 1 method)

julia> @enter f()
In f() at REPL[3]:1
 1  function f()
>2      x = g()
 3      println(x, "hello")
 4  end

About to run: (g)()
1|debug> bp add println
[ Info: added breakpoint for function println

Ah, I confused print and println in this example, but I still don't see why QuoteNode shows up here?
