    tdf#108682 DOCX import: fix <w:spacing w:line=...> for negative values
    
    I didn't find UI in Word to create
    
    <w:spacing w:line="-260" w:lineRule="auto"/>
    
    the equivalent markup when you set line spacing to exactly 13pt for new
    documents is:
    
    <w:spacing w:line="260" w:lineRule="exact"/>
    
    The OOXML spec and Microsoft's implementer notes ([MS-OI29500]) is also
    pretty silent about what a negative value means. However, if this markup
    is converted to WW8 by Word, then the WW8 LPSD structure is like this
    (as presented by doc-dumper):
    
    <lspd type="LSPD" offset="5086">
      <dyaLine value="0xfefc"/>
      <fMultLinespace value="0x1"/>
    </lspd>
    
    For the 0xfefc value the [MS-DOC] spec clearly states that means the
    type of the spacing is "exactly", with the value of 0x10000-0xfefc, i.e.
    the same 260 twips.
