We could pass the prefix argument to `indent-region' with the semantics
that the latter ignores the mode-specific `indent-region-function' and
calls `indent-line' for each line in the region instead.

Alternatively, `python-indent-region' could, like `python-indent-line',
remember whether the last command was an `indent-for-tab-command' and
call `python-indent-line-1' with no argument for each line in the
region.  Obviously, the region would have to stay to make this
practical.  And in some pathological cases it might be hard to find the
appropriate indentation points.

Anyhow, I'm afraid that people won't approve such changes.

That's why I earlier said that some rectangle code should handle this.
