That looks pretty good, thank you.
Fabián, could you take a look?

The idea is good but the patch needs bit more of work -- this approach
will work when an indented region is sent but won't when sending a
region which starts with no indentation at all. Also backtraces numbers
will be wrong for a -1 offset.

I'll push something for this soon.

Fabián.

Right. Current python-mode.el shifts region-or-whatever-delivered left until it starts at column 0.

Correct. BTW there is still the Emacs count-lines bug: at BOL it counts one less than from secoond column.

Fabian,

You are correct on both counts.  Please let me know if I can be of
assistance to you.  Thanks for your time and effort.
