Hi.

I noticed that if I have the following Makefile

```
define test_function
        echo $(1) \
                $(2) \
                $(3)
endef

.PHONY: test_function
test_function:
        $(call test_function,1,2,3)

.PHONY: test
test:
        echo 1 \
                2 \
                3
```

If I run `make test -n`, I will get my expected multiline human readable
output

```
✗ make test -n
echo 1 \
        2 \
        3
```

If I run `make test_function -n`, all of the commands will be 

```
✗ make test_function -n
echo 1 2 3
```

People have found some odd workarounds
