With emacs 26.3.
There are two related bugs which makes python-shell-send-defun
sometimes not send the right contents.
== reproduce the first one ==
$ emacs -Q /tmp/newfile.py
C-c C-p [start python process]
def foo(): RET [define a ...]
pass RET [... python function]
C-M-x [python-shell-send-defun]
In the echo area it says "Sent: pass..."
because only that line was sent. Not the whole definition, and the
function is not defined in the inferior python.
A variant is to have a line "@property" before the "def foo():" line.
Then python-shell-send-defun will enter an infinite loop instead.
== reason ==
python-shell-send-defun moves lines backwards one at a time until it
is out of the defun, and then (forward-line 1) to go back into it.
When the file begins immediately with the first defun (which isn't that
common, since normally there'd be a shebang or other comment there)
it never goes outside of the defun so then (forward-line 1) is wrong.
== fix ==

$ emacs -Q testfile.py

----------------------
def foo():
pass
@property
def bar():
pass
----------------------
C-c C-p [run-python]
M-> [end-of-buffer]
C-M-x [python-shell-send-defun]
In the echo area it echoes "Sent: ..." and "bar" is not defined in the
inferior python which it should be.
== reason ==
When python-shell-send-defun goes to the beginning of the defun it goes
to the line with "@property", but from there python-nav-end-of-defun
doesn't find the end of that defun.
== fix ==
This could be seen as a bug in python-nav-end-of-defun and be fixed
only there instead. I haven't done that.
This patches this for python-shell-send-defun (including
the patch one above), which might be a good idea anyway, making
python-shell-send-defun more robust by going to the end-of-defun from
the original position and not from where it ended up looking for the
beginning.
(The fix is really small except for the indentation changes.)
