consider dropping -r option

[garlick]

Problem: the -r option causes a file to be removed after scrubbing, but this action is ambigous when scrubbing a symlink (do you remove the link, the target, both)?

Rather than guess what the user wants, maybe just let them remove their own files? How hard is that.

In my PR #33 , both are removed. Currently, scrub will follow the link, scrub the target, but it will remove only the link! This is weird. Also with -D, it will rename the link, not the target. -r is useful for removing traces of the scrub.

But I won't cry or argue if both disappear. After all, anyone using this application had BETTER know what he/she is doing! ;-)
