[bv-dev] Name for path nodes representing return values

[Hardy Ferentschik]

Hi,

I always liked $retval or maybe just retval. In the end we are also using arg0, arg1, etc. I like the shorter retval better than returnValue, because I think it fits better with arg<number>.
The '$' tried to denote somehow that this is a special name value, but I guess this could be just dropped.
