[PATCH] t4011: modernise style

[Junio C Hamano]

Match the style to more modern test scripts, namely:

 - The first line of each test has prereq, title and opening sq for the
   script body.  This makes the test shorter while reducing the need for
   backquotes.

 - Be prepared for the case the previous test may have failed.  If a test
   wants to start from not having 'frotz' that the previous test may have
   created, write "rm -f frotz", not "rm frotz".

 - Prepare the expected output inside your own test.

 - The order of comparison to check the result is "diff expected actual",
   so that the output will show how the output from the git you just broke
   is different from what is expected.

 - Write no SP between redirection '>' (or '<' for that matter) and the
   filename.

Hi Junio.

I've noted a possible typo in the commit message ...

Did you intend "backslashes" instead of "backquotes" here?

  Stefano

Thanks.  I did have this funny feeling in my butt while writing it, but
didn't quite realize what was wrong ;-)

Will fix.
