Hi Ilya,

thanks for reports and the patch. However, I believe that
patch takes a wrong 
approach to the problem. The syntax of target references is
parsed in 
project-target.find-really method. It would be logical to
check that the part 
before '//' is not empty in that method.

What do you think?

path.make-NT rule returns nothing ("") for paths
