Hello,

`python-shell-send-region' fails with the following error when the
region starts in the middle of the first line.

Wrong type argument: wholenump, -1

This is caused by the code to insert the coding cookie in
`python-shell-buffer-substring'.  I think that the current code
assumes that the region begins at line beginning position.  However,
there are some use-cases where the region starts in the middle of the
line as discussed in #60142.  So I think the special treatment in case
of point-min should be extended to case of first line.  Attached is a
patch to implement this.
