[PATCH v6 1/3] t4001: modernize
Old tests were written in a different style than modern
ones; for better readability and test error messages,
update t4001 to the modern style. * run everything inside of a test_expect_success block.
* write title line on the same line as test_expect_success,
end that line with a single quote that opens the body of the test,
and end the test with a single quote that closes the body.
* write expected output of a test to a file named "expect",
and actual output to a file named "actual".
* write here-docs using "<<-" syntax, so that they're indented
uniformly with the rest of the test.
* make test names more clearly reflect the functionality that
they test.Signed-off-by: Mark C. Chu-Carroll <markchucarroll@fastmail.com>
