How to see git log on the given moved file with diffs

Yes, I can do that with help of next command:

$ git log -p -M
commit 9841f31f283c74ec9e2a33869590d976091cf191
Author: user
Date:   Sat Apr 4 09:58:12 2015 +0300

    Move file

diff --git a/test.pl b/test/test.pl
similarity index 85%
rename from test.pl
rename to test/test.pl
index dd0479d..0d880c8 100644
--- a/test.pl
+++ b/test/test.pl
@@ -2,4 +2,5 @@

 use Modern::Perl;

+#comment
 say "Hello, world";

But in my case I have handred files, so I want to restrict log messages to certain one

$ git log -p -M test.pl 
commit 9841f31f283c74ec9e2a33869590d976091cf191
Author: user
Date:   Sat Apr 4 09:58:12 2015 +0300

    Move file

diff --git a/test/test.pl b/test/test.pl
new file mode 100644
index 0000000..0d880c8
--- /dev/null
+++ b/test/test.pl

As you can see diff --git a/test/test.pl b/test/test.pl git do not recognize rename in this case.

Is that the git BUG or must I use different options?

ANSWER just want to show output in my case:

$ git log -p --follow test.pl
commit 9841f31f283c74ec9e2a33869590d976091cf191

rename from test.pl
rename to test/test.pl

--- a/test.pl

@@ -2,4 +2,5 @@

If you notice, with this flag --follow diff do right thing:

diff --git a/test.pl b/test/test.pl

I think what you want here is the --follow option

  --follow
      Continue listing the history of a file beyond renames (works only 
      for a single file).

Try git log -p --follow test.pl.

An example in a test repository looks like:

commit 16da3d589da102e11c822b0bec931eed41c35e25
Author: John Szakmeister <[email protected]>
Date:   Sat Apr 4 04:19:51 2015 -0400

    rename and add *

diff --git a/foo.txt b/bar.txt
similarity index 92%
rename from foo.txt
rename to bar.txt
index 0ff3bbb..e431201 100644

Without --follow, you get:
