Bug #11021: FileUtils.mv displays the wrong destination when Errno::EEXIST is raised
https://bugs.ruby-lang.org/issues/11021#change-52267

* Author: Jo��o Britto
* Status: Closed
* Priority: Normal
* Assignee: 
* ruby -v: ruby 2.2.1p85 (2015-02-26 revision 49769) [x86_64-darwin14]
* Backport: 2.0.0: REQUIRED, 2.1: DONE, 2.2: REQUIRED
----------------------------------------
Suppose we have the following directory structure:

~~~
$ cd /tmp
$ mkdir -p ruby/a
$ mkdir ruby/a/b
$ mkdir ruby/b
$ tree ruby
ruby
��������� a
������� ��������� b
��������� b

3 directories, 0 files
~~~

When we try to move `b` inside `a`, there is a name clash and `Errno::EEXIST` is raised.

~~~
$ irb
>> require 'fileutils'
=> true
>> FileUtils.mv 'ruby/b', 'ruby/a'
Errno::EEXIST: File exists - ruby/a
~~~

However, the error message says `ruby/a exists`, which does not seem to be the proper destination. The error message should instead read `ruby/a/b exists`.

I am including a patch to address this issue.
