    Revert link alignment fix in favor of head indent support

    This partially reverts commit 843d390.
    Breaks fix for Issue #376.
    Implemented fix for #376 breaks first line head indent functionality
    without a workaround possibility. Link alignment can be fixed pretty
    easily using paragraph attributes.
