rev-parse test: modernize quoting and whitespace

Instead of cramming everything in one line, put the test body in an
indented block after the opening test_expect_success line and quote
and put the closing quote on a line by itself.

Use single-quote instead of double-quote to quote the test body
for more useful --verbose output.
