Possibly but I don't think so.  In order for it to match, the patterns
have to match.  If the target matches "foo.min.js" so that the pattern
is "foo", then the prerequisite can't be "foo.min.js" as well.  It can
only be "foo.js"

So, if your prerequisites of "all" are foo.min.js and bar.min.js, no
confusion results: it will try to build based on foo.js and bar.js.

Certainly if you do something like "all: $(wildcard *.js)" then badness
will ensue... but no one would do that right?

Heh.  That's not me :-)
