[PATCH 6/7] t1303 (config): style tweaks

[Jonathan Nieder <jrnieder@gmail.com>]

This test already has impeccable style, with one exception: there
is an unnecessary use of a subshell.  Use a {} block instead.
While at it:

 - guard setup commands with test_expect_success, so the commands
   are printed when the test is run with "-v" and errors in setup
   can be caught;
 - use echo instead of printf to print simple text ending with a
   newline, so the later use of printf stands out more;
 - put a single space before () in function definitions, for
   consistency with other shell scripts in git;
 - reorder arguments to test_cmp as "test_cmp expected actual".
