tdf#120703 (PVS)

V668 There is no sense in testing the 'pBuf' pointer against null, as the
     memory was allocated using the 'new' operator. The exception will be
     generated in the case of memory allocation error.

V547 Expression 'ePageKind == PPT_NOTEPAGE' is always true.

V581 The conditional expressions of the 'if' statements situated alongside
     each other are identical. Check lines: 3724, 3727.

V1023 A pointer without owner is added to the 'aCharPropList' container
      by the 'emplace_back' method. A memory leak will occur in case of
      an exception.
