I think the best kind of << or >> would be ones that prevent "shell
script injection attacks". Is there some usable lowest common
denominator between the escapes used by various shells?
Platform-specific output and a permissive parser might work too.
Remembering the Requirement to "Be able to write portable script-style
filesystem operations in modern C++"
there should be some way to stringstream together something that can
be safely passed to std::system.
Imagine something like this:
path p = "-f x";
ss << delete_program << " " << p;
It'd be great if it became system("rm './-f x'"); or similar, avoiding
all kinds of pitfalls in the process.
