 python-nav-forward-block moves backward under certain conditions.

[Message part 1 (text/plain, inline)]

Hi,

The following steps move the point backward to the beginning of the line.

1. emacs -Q
2. Load the following Python file using M-x find-file

#+begin_src python
if True:
    pass
#+end_src

3. M-x forward-char
4. M-x python-nav-forward-block

This happens when:

- point is on the block-start line of the last block,
- point is at least one character after the beginning of block-start, and
- searching forward (positive ARG for python-nav-forward-block).

Attached is a patch to fix this issue.

Best Regards,

--
