Hi Andreas, Anton,

Indeed, I agree that this could be very useful in some situations.  It can be
a little distracting, so it probably should not be turned on by default, but
for those cases where the indentation is really hard to follow, I think this
could be a very nice addition.

Is this file going to be added to Emacs?  It seems more general than just for
Python (e.g. turn it on in python-mode.el).

One minor nit: I wonder if it makes sense to highlight columns that are not in
the leading whitespace.  For example, turn it on and look at the define-key
lines starting at about line 845 in python-mode.el.  There are some
highlighted indentation extents after the "\C-c:" string.  Those don't seem
useful.

Thanks for pointing it out, and thanks to Anton for writing it.

Cheers,
-Barry
