Replace the above 2 forms with:

	verbose test "$(cat file)" = expected
Quoting is very much a good idea, but I am not enthused by the
vision of having to write verbose everywhere in our script.

After seeing a script fail, you can run it again with -i -x options;
wouldn't it be sufficient?
Just to avoid misunderstanding, I am unhappy if we have to keep
writing "verbose test" in that exact form.

Just like we invented to help debugging by wrapping "cmp" with
"test_cmp" (i.e. we want to see if the file contents are the same,
but a person who debugs can be helped by seeing the differences when
the expectation is not met), I do not mind if we had a shorter and
cleanly-named wrapper that we can use consistently.  E.g. I do not
mind something like this in test-lib-functions.sh

	test_file_contents () {
		if test "$(cat "$1")" != "$2"
		then
			echo "Contents of file $1 is not $2"
                        false
		fi
	}

and used like so:

	test_file_contents file expected_string
