Feature #2988: inconsistent array flattening

Branch:
arrays are not flattened when defined using array variables, but they are
flattened when arrays are defined in the array.
I wanted at least document this inconsistent behavior, below, c != d (at least
from the perspective of templates).
#test.pp
<pre>
$a = ['a1', 'a2']
$b = ['b1', 'b2']
# c is not flattened
$c = [$a, $b]
# d is flattened
$d = [['a1', 'a2'], ['b1', 'b2']]
file {'/tmp/arrayflattest':
content => template('/etc/puppet/templates/arrayflattest.erb'),
}
</pre>
#arrayflattest.pp
<pre>
<% c.each do |val| -%>
c val: <%= val %>
<% end -%>
<% d.each do |val| -%>
d val: <%= val %>
<% end -%>
</pre>
#arrayflattest
<pre>
c:a1a2
c:b1b2
d:a1
d:a2
d:b1
d:b2
</pre>
