Bug #5517: behavior change within 2.6 makes it impossible to override class
parameters of "included" parametrized classes

In 2.6.1 the following recipe:
<pre>
class a(
$b_c = { 'b' => 'foo' }
) {
notice $a::b_c
if $a::b_c {
notice $a::b_c['b']
}
}
class b {
class{'a': b_c => false }
}
class b::c inherits b {
Class['a']{ b_c => { 'b' => 'bleh' } }
}
class b::d {
include ::b::c
}
include b::d
</pre>
produces the following output:
<pre>
$ puppet foo.pp
notice: Scope(Class[A]): bbleh
notice: Scope(Class[A]): bleh
</pre>
Which is what I expected. However with 2.6.3 it produces the following output:
<pre>
# puppet foo.pp
notice: Scope(Class[A]): false
</pre>
Imho like the changes for #4778 and #5074 are responsible for that behavior
change.
However this makes it impossible to overwrite parameters of a "included"
parametrized class in a subclass. There are only ugly workarounds for that
problem and I think this should actually work as it did within 2.6.1. Otherwise
the usefulness of parametrized classes is quite reduced.
