It's also to create a lowercase macro that does $(shell tr '[A-Z]'
'[a-z]'), explaining that the 'ugly' non-tr implementation is not
needed because lowercase isn't called that often.
The reason that I like the centralization is that you can make one
correct implementation, and other people won't make the
forgotten-quote mistake a second time.
Also, I think [A-Z] should be replaced by [:upper:] and [a-z] by
[:lower:] as this is more generally correct.
