[svn-r21380] 
Ported shape same test express test mods from trunk to 1.8 branch.

This was mostly a matter of copying testpar/t_shapesame.c from trunk
to the 1.8 branch, as the root versions of the files were almost 
identical.

Tested parallel on Jam only, as changes have been well tested on the 
trunk.
