It was working fine, but the style wasn't exactly the way I like it, because
I'm unnecessarily picky. :)
Also, removed the file extension since we should probably learn from the
fact that it's already been rewritten once from one language to another.
Who knows, maybe it will be again someday.
This comes down to the lack of a 'seq' command (what?!) and the fact that
BSD "wc -l" returns extra whitespace, while the GNU version doesn't. We
should be using numeric comparisons instead of string comparisons, and then
it's ok.
...only when running under minimal/do, of course.
The tests in question mostly fail because they're testing particular
dependency-related behaviour, and minimal/do doesn't support dependencies,
so naturally it doesn't work.
It actually decreases readability of the .do files - by not making it
explicit when you're going into a subdir.
Plus it adds ambiguity: what if there's a dirname.do *and* a dirname/all?
We could resolve the ambiguity if we wanted, but that adds more code, while
taking out this special case makes *less* code and improves readability.
I think it's the right way to go.
We had a bug (fixed in the previous commit) where doing 'redo-ifchange
dirname' (which runs dirname/all.do) would not create the stamp correctly,
so that it would always show up as dirty.
It's a little bit complicated to simulate, but this does it.
