add failing spec for issue #6
Comments and line breaks inside ConditionalExpression. Fixes #6

Removes the removal of line breaks, since we don't know when
those should be added back. Instead the consequent and alternate
after a line break are indented properly. Accordingly I had to remove
the line breaks in single-line test.

Getting comments to intend properly as well required a special
path within indent.getCommentIndentLevel. All attempts to modify
the existing logic failed to provide useful results. Instead of now
applies the same logic to figure out the level as for the code itself.
