Follow-up Comment #1, bug #50376 (project make):
In 2010's make-3.82, which is where this behavior changed, and later releases,
the rule appears like this in make -p:
my_dir/hello.txt: | my_dir/
In make-3.81, it didn't have the trailing slash. $(dir) still produced a
trailing slash there. From printf debugging, I think the trailing slash was
being removed by the call to multi_glob in parse_prereqs, as it was then
called. That was removed by this part:

- Add xcalloc() and call it - Fix memory errors found by valgrind - Remove
multi_glob() and empower parse_file_seq() to do its job: the goal here is to
remove the confusing reverse/re-reverse we do on the file lists: needed for
future fixes. - Add a prefix arg to parse_file_seq() - Make concat() variadic
so it can take arbitrary #'s of strings
