I stopped using -R PATH and -F PATH because it was clear that
debuginfod would be more comfortable to use with PATH lists
constructed from the full powers of the shell - just like 
most other unix programs.  This is not just glob expansion,
but things like backquote expressions that grep things, or
via xargs.  Let's leave the shell to do shell things.
