t3400 (rebase): whitespace cleanup

This test used 5-space indents since it was added in 2005, but
recently the temptation to use tabs to indent has been too
strong, resulting in uneven whitespace.  Switch over completely
to tabs.

While at it, use a more modern style for consistency with other
tests:

 - names of tests go on the same line as test_expect_success;
 - extra whitespace after > redirection operators is removed.
