Revision 197539

For area.Blocks created in BlockLayoutManager.getParentArea(), I set the
width of the Block to that of its parent block.

This fixes a layout problem where

<fo:table-cell><fo:block border-bottom="1pt solid black">some text</ ></ >

was causing a line to draw across the entire page, because the cell width present in
fo:table-cell's Block was not copied into the inner fo:block's Block.  (This problem did not
occur if the border-bottom attribute was set in fo:table-cell.)
