depth => 0 is ignored by perms file attribute

In the following code, recurse_with_base("0") and recurse_with_base("1") have the same effect. All the content of the base directory is affected in addition to the base itself, whereas the expected action for depth 0 is to affect only the base directory.

<pre>
files:
"/home/amousset/perms"
create => "false",
perms => mog("640", "amousset", "root"),
depth_search => recurse_with_base("0");
</pre>

Before:

<pre>

1. ll -R perms
   perms:
   total 4.0K
   drwxr-xr-x. 2 root root 4.0K Jun 24 16:08 dir/
   rw-rr-. 1 root root 0 Jun 24 16:08 file

perms/dir:
total 0
rw-rr-. 1 root root 0 Jun 24 16:08 file
</pre>

After running the previous example:

<pre>

1. ll -R perms
   perms:
   total 4.0K
   drwxr-x---. 2 amousset root 4.0K Jun 24 16:08 dir/
   rw-r----. 1 amousset root 0 Jun 24 16:08 file

perms/dir:
total 0
rw-rr-. 1 root root 0 Jun 24 16:08 file
</pre>

The problem does not exist for example with copy_from (the copy of the content of the base directory is not made if depth is set to 0).
