- #6e60ef0

Reason
------
The indent functions, in this case
      GetPythonPEPIndent()
can modify the cursor position. There is nothing wrong with that
consequence, vim takes it into account and restores the cursor
position (see References below). For the tests vim is not doing
the calling, so the cursor is not restored.

Solution
--------
Restore the cursor position after calling the indent function.

Fix issue #5 (Correct indent after end of block)

Problem
-------
Given two adjacent blocks where the 2nd block has
an equal or smaller indentation level compared to the 1st
block. If the blocks are not separated by an empty line,
the 2nd block will be placed (indented) inside the 1st
block.

This changes the meaning of code that already adheres to the
pep8 standard.

Solution
--------
Do not inherit indentation of the previous line if the current line
has less indentation but is valid.
