related to your last commit, sort_by is neccesary becouse its expected order values.

I see two type of errors

     Failure/Error: (lines & Array(param[:match])).should == Array(param[:match])
       expected: ["    allow test value 3;", "    test1 test value 1a;", "    test1 test value 1b;", "    test2 test value 2;", "    test4 subtest1 \"sub test value1a\";", "    test4 subtest1 \"sub test value1b\";", "    test4 subtest2 \"sub test value2\";"]
            got: ["    allow test value 3;", "    test1 test value 1a;", "    test1 test value 1b;", "    test2 test value 2;"] (using ==)

This is caused by different spacing

<% if @location_custom_cfg_prepend -%><% @location_custom_cfg_prepend.each do |key,value| -%>
<% if value.is_a?(Hash) -%><% value.each do |subkey,subvalue| -%>
<% Array(subvalue).each do |asubvalue| -%>
   <%= key %> <%= subkey %> <%= asubvalue %>;
<% end -%>
<% end -%><% else -%>
<% Array(value).each do |asubvalue| -%>
    #<%= key %> <%= asubvalue %>;
<% end -%>
<% end -%>

I replaced the extra space with # to highlight it

     Failure/Error: (lines & Array(param[:match])).should == Array(param[:match])
       expected: ["    allow test value 3;", "    test1 test value 1a;", "    test1 test value 1b;", "    test2 test value 2;", "    test4 subtest1 \"sub test value1a\";", "    test4 subtest1 \"sub test value1b\";", "    test4 subtest2 \"sub test value2\";"]
            got: ["    allow test value 3;", "    test1 test value 1a;", "    test1 test value 1b;", "    test2 test value 2;", "    test4 subtest2 \"sub test value2\";", "    test4 subtest1 \"sub test value1a\";"] (using ==)

In this case seems not render test4 subtest1 "sub test value1b"; but all test that i did it was render fine and i cant resolve it :(

Opps. forgot to push the revert. Done now.

1. ... spacing

fixed in two places.

:( yep, saw that. I can't see the cause either.
