I expected to make no changes and get some messages, but got a change
and no messages.

The Reference manual
(http://www.ruby-doc.org/stdlib/libdoc/fileutils/rdoc/classes/FileUtils/DryRun.html)
said that “never changes files/directories”.

I think this mismatch between documents and actual behavior is harmful.

A easiest way to resolve the problem is to remove methods which does not
accept ‘noop’ option from FileUtils::DryRun.
