commit db04be037b611e296ef9f2542322c52ed82d7a2b
Author: Mike Kaganski <mike.kaganski at collabora.com>

    tdf#35798: Hide empty Database fields' paragraphs (+ compat option)
    
    With this change, Database fields that expand to empty values behave
    as if they are "Hidden Paragraph" fields.
    
    A compatibility option to enable this behaviour is added. The option is
    enabled by default, and for any non-native documents (for compatibility
    with other office suites). For existing (F)ODT documents, the option is
    disabled for those documents that don't have this setting set, to keep
    the layout of legacy documents.
