Fix over-reindentation when o/O continues comments

This would run indent-according-to-mode after creating a new line, which
would often throw new comment lines out of whack. Now it preserves the
indentation of the originating line.

Also fixes continuation whitespace issues with evil-open-above on
C-style block comments.
