I've put together this prototype to offer more useful messages in the
situation Oliver describes.
Subsequent calls to the same portal are described as FETCHes rather than
as EXECUTEs. The portal name is still given and number of rows is
provided also.
I haven't tested this with the java program supplied, since this is a
fairly short-hack for comments. I'll correct any mistakes before
submission to patches.
Comments?
