Originally it was not _guaranteed_ that wildcard yields sorted output.

However, the output did happen to be sorted in older versions of GNU
make.  In GNU make 3.82, that was changed to yield unsorted output.  As
of GNU make 4.3, it was changed back and it is now guaranteed that
wildcard results are sorted:

I thought that I had updated the documentation to make this guarantee
clear but perhaps I forgot?
