Unfortunately I had to revert that patch, since it risks removing
directories when the second argument (`to') is a directory.  For
example, eggs that depend on setup-helper trash `(chicken-home)', since
setup-helper runs

 (when (setup-install-mode) (copy-file "setup-helper.scm" (chicken-home))

at some point.

Thanks to Peter Bex to help investigating and pointing out what was
causing the problem.

I've reopened #929.


Best wishes,
Mario
