I've long thought that we should, eventually, support the latter use.
It seems to have a clearly defined meaning.  And it is even useful in
some situations.  For instance, suppose in a very large project you
want to `include' some boilerplate.  Then you might conditionally
override some value or another in a particular Makefile.am.

Before Akim's rewrite of variable handling, we really couldn't do
this.  We just didn't have the internal abstractions.  Now it might be
possible, but I haven't looked.
