Probably the right way to do it is to write a Sys.legal.filenames()
function that takes a vector of strings and creates legal filenames
out of them.  I'm not sure what optional args it would want, but
possibilities are

  - Avoid existing filenames.
  - Do it in a certain path.
  - Do it in a way that's likely to be portable to other systems.
  - Create filenames that are convenient, not just legal (e.g. even on
Unix, don't allow asterisks or other characters that shells pay
attention to; on Windows, avoid embedded spaces, etc.).
