I'm not sure if this is what Peter is asking about, but I have a situation
where I'd like to be able to insert line feeds myself:

Consider this Makefile:
--------------------------------------CUT---------------------------------------
HFILES = \
        foo.h \
        bar.h \
        baz.h

PRODUCTION_LOCATION=/auto/include

diff:
        @$(foreach file, $(HFILES),diff $(PRODUCTION_LOCATION)/$(file) $(file);)
--------------------------------------CUT---------------------------------------

make -n diff looks like this:

diff /auto/include/foo.h foo.h; diff /auto/include/bar.h bar.h; diff 
/auto/include/baz.h baz.h;

it would be easier to read (especially for a large number of .h files if
it would look like this:

diff /auto/include/foo.h foo.h;
diff /auto/include/bar.h bar.h;
diff /auto/include/baz.h baz.h;

But I haven't been able to come up with a way to insert a line-feed into
the output.
