Yes, it's the wrong way around. The indentation should be determined by
the start quote. That's why I initially wrote that the quotes must
line up vertically.
Unfortunately you can't write
a_multi_line_string =
i'''
Py-
thon
'''
although you can write
a_multi_line_string = \
i'''
Py-
thon
'''
which is visually not much worse.

Eek! No, I don't think that's a good idea. It means that the programmer
has to count spaces and has to remember to adjust the parameter if the
indentation changes (e.g. because the block is wrapped in a loop or
factored out to a function).

The default should be the minimum number of leading spaces on non-empty
lines, I think. This is compatible with PEP 257. And in fact it allows
all lines to start with whitespace if the string ends with a newline
(which is a weird dependency, but probably not much of a restriction in
practice).

This looks like overkill to me. What would be the use case?

Everybody has their own definition of "pythonic", I guess.
