SwGluePortion::GetPrtGlue() can legitimately be larger than 'short`
At least during JunitTest_sw_unoapi_4
sw.SwXTextTable::com::sun::star::text::TextTable::TableColumnSeparators,
some
SwFormatFrameSize is created with a width of USHRT_MAX ("Set USHRT_MAX as
the
Table's default SSize") in SwDoc::InsertTable
(sw/source/core/docnode/ndtbl.cxx). In SwTabFrame::Format
(sw/source/core/layout/tabfrm.cxx) that leads to nWishedTableWidth with a
value
near USHRT_MAX and substantially larger than nMax, causing nLeftSpacing to
be a
large negative value in the text::HoriOrientation::CENTER case. That in
turn
causes SwTextAdjuster::CalcRightMargin (sw/source/core/text/itradj.cxx) to
set
pRight->PrtWidth( sal_uInt16( nRealWidth - nPrtWidth ) );
with a value of 32768 (where pRight is a SwGluePortion). And a later call
to
that SwGluePortion's GetPrtGlue would try to convert that 32768 to 'short',
getting flagged by Clang's -fsanitize=implicit-signed-integer-truncation.
In addition to changing GetPrtGlue (and MoveGlue) to use 'long' instead of
'short', drop some unncessary narrowing casts from client code.
