    tdf#158658 sw: text formatting: make TabOverMargin even more crazy
    
    ... to better match Word's formatting.
    
    The bugdoc has a special case where a right-aligned tab is positioned at
    the right margin exactly, which causes the bFull condition in
    SwTabPortion::PreFormat() to be true.
    
    An obvious change to replace rInf.Width() - rInf.X() with
    rInf.GetLineWidth() in the condition makes no difference because
    m_pLastTab was already reset previously; instead, pass in the last tab
    from Format(), which indicates that the right edge position of the
    previous text portion was found via that tab.
    
    Additionally, change the condition that checks for TabOverMargin to also
    allow equal positions, i.e., exactly at the end of the paragraph.

    tdf#158658 sw: text formatting: try to make TabOverMargin more crazy
    
    ... to better match Word's formatting; this commit is not based on a
    complete diagnosis of Word's compatibility-mode tab-in-margin
    formatting disorders.
    
    1. in SwTabPortion::PreFormat() allow a left aligned tab beyond the
       width of the paragraph, like already done for TabOverSpacing
    
    2. in SwTextFormatInfo::GetLineWidth() add some extra width to the
       paragraph so text can be hidden in the right margin.
       (it's very unclear what Word does here exactly, in one case it puts
       339 additional "a" characters in the margin but then the 340th "a"
       goes onto a new line...)
    
    3. in SwTextFormatter::NewTabPortion() allow manual tab stops to be
       positioned beyond the width of the paragraph, like already done
       for TabOverSpacing
    
    testTdf118672, testTdf120287b, testTdf120287c fail but the files,
    converted to RTF, render in Word 2013 basically the same as in Writer
    with this change.
