Subject: Refix issue #5 (Correct indent after end of block)
X-Git-Url: https://git.madduck.net/etc/vim.git/commitdiff_plain/445ce093b0aaaf767b18c052edbe688e82d18480?hp=9370cda99be0cfe529c40e5c6ce48ef01940a266

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

The implementation clean up reintroduced a more severe
version of the bug. Plus, the test was slightly deficient
to catch the regression.

Problem
-------
Given two adjacent blocks where the 2nd block has
an equal or smaller indentation level compared to the 1st
block. If the 1st block does not end in a stop statement
it always sucks up the 2nd 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.
