[issue19155] Display stack info with color in pdb (the "w" command)

New submission from Peng Yu: Currently, the "w" command does not show the stack info in color. I think that it might be visually helpful to add some color to emphasize the current frame, etc. May I suggest to add this feature to pdb? Thanks. -- messages: 198916 nosy: Peng.Y
