Extra space on blank lines is a matter of preference. Personally, I think it is easier to edit files that have extra spaces on blank lines. This way, when you click on a blank line, the cursor is positioned at the proper place to start typing. If the extra space is removed, you need to tab to the correct location (or hit return to force auto-indent) before typing.
@utenmiki thanks for the pull request!
