t9700: modernize test scripts

The style of t9700-perl-git.sh is old. There are 3 problems:
* A title is not on the same line with test_expect_success command.
* A test body is indented by whitespaces.
* There are whitespaces after redirect operators.

Modernize test scripts by:
* Combine the title with test_expect_success command.
* Replace whitespace indents with TAB.
* Delete whitespaces after redirect operators.
