Just to be clear, I thought that was the only kind under
consideration.  I don't think there's any way we could implement
wildcards at make time.

It happens all the time for test suites.  For instance, automake's.
Or any of several that appear in gcc.

Also this happens a lot in libjava, where we sometimes add a new .java
file without touching anything else.  I imagine the same is true for
many Java libraries.

For automake I often make test cases I don't check in.  Having these
be picked up in would be pretty bad -- it would break the
build.  So the next step will be someone suggesting that $(awildcard)
needs to know how to look at CVS files only.  Bleah.  (This is a glum
prediction, not an actual argument against -- we can always say "no"
when that comes along.)

That said, I'm still open to understanding why people want this.  Are
there projects where adding a new line to is a significant
burden?  What's an example of one?
