Careful on the // case, for systems like cygwin where // is a distinct
root from / (it has a separate inode, but should likewise be forbidden
to recursively delete from // - hmm, I don't know that I've ever been
brave enough to actually test whether --preserve-root preserves // on
cygwin).
Also, if a user does 'ln -s / root' and does 'rm -r root/.'
(technically, this should also be done for 'rm -r root/', but Linux
doesn't obey POSIX with regards to 'rm symlink-to-dir/').
