I've checked for duplication, but this is effectively new code. pre-3.0
code in jar.py did not do anything like this. The post 3.0.1 jar.py
changes help other problems I have, but not this one.

The problem is in a simple check, os.path.isfile(), which is not safe to
do in the context of a variant dir (without copying), because the source
files in the working/variant directory exist only in the mind of SCons,
not Python. As noted in the bug, I don't at the moment know how to apply
a transformation to convert back to the source directory in the context
in which the tool runs, so figured it was best to document it.
