Ah... ok. I don't distinguish between the two.

It's certainly still evil.

The problem is that 'normalize-raw-paths' does something less --- it cannot
join two paths together. I'll probably see how path.join can be improved, by
anyway: unless path.jam is moved to "kernel", "modules.jam" cannot benefit

Why not "cvs rm -f tools/new/something.jam"? Or just "rm
