This fixes the text alignment:
(just replace te appropriate code in 
toggle_code_context_event with this)

        if not self.label:
            self.padding_frame = Tkinter.Frame(self.editwin.top,
                                               bg=self.bgcolor,
                                               border=2,
                                               relief="sunken",
                                               )
            self.label = Tkinter.Label(self.padding_frame,
                                       text="\n" * (self.numlines - 1),
                                       anchor="w", justify="left",
                                       font=self.textfont,
                                       bg=self.bgcolor, fg=self.fgcolor,
                                       border=0,
                                       width=1, # Don't request more 
than we get
                                      )
            self.label.pack(side="top", fill="x", expand=1,
                            padx=4, pady=0)
            self.padding_frame.pack(side="top", fill="x", 
expand=0,
                                    padx=0, pady=0,
                                    after=self.editwin.status_bar)
        else:
            self.label.destroy()
            self.padding_frame.destroy()
            self.label = None


Sorry it's not a diff...
