One of the reason I use e.g. File.cp(source, dest) rather than `cp
#{source} #{dest}`, is that people willing to port the code to a
platform where there is no `cp' in the path won't spend hours
searching and replacing.

I don't know if `.' and `..' in listings produced by Dir actually
cause portability problems.  If so, I'm for leaving them behind.
