This is entirely outside the scope of this series, but we may want
to see if it makes it easier to read and maintain to turn executable
part of test_expect_success that is double-quoted to use single
quotes around it instead for many of our tests.

This one is a prime example of it.  I do not think the executable
part is getting _any_ benefit from being quoted inside double-quote
pair.  All the single quoted strings it uses in the script commands
(e.g. the argument to "git commit -m") can equally be quoted with
double quotes safely, and there is no $variable reference that it
wants to refer to the value of the $variable when the command line
of test_expect_success itself is constructed.
