                 Summary: Var wrongly declared undefined

Details:

When running the following (modified code from MUnit framework)
== file CollectTests.m ==
function ts = CollectTests(files,recursive,name)
  if isa(files,'char')
    ts = CollectTests({},recursive,name);
  else
    tests = cell(1,numel(files));
    disp(tests);
    ts = testset(name,name,tests); % fails when using this line
%     ts = makeTS(name,name,tests); % works when using this line
  end
end

function ts = makeTS(name,id,tests)
    ts = testset(name,id,tests);
end
=======

I get:
octave:3> CollectTests('hello',true,'hello')
{}(1x0)
error: `tests' undefined near line 7 column 28
error: evaluating argument list element number 3
error: called from:
error:   D:\tests\libs\MUnit\tools\CollectTests.m at line 7, column 8
error:   D:\tests\libs\MUnit\tools\CollectTests.m at line 3, column 8


Note that 'tests' is displayed a line above where it is used, it is not
undefined but {}(1x0) instead.

The call works correctly, when the construction of the testset class is
deferred to another function in the same file (uncomment line 8 and comment
line 7)

The recursion one CollectTests seems to be important: calling directly
works:

octave:3> CollectTests({},true,'hello')
{}(1x0)
Unit test "hello" of class "testset",
        hello

Both tests are made right after clean start of octave, while only the path
has been set. 
testset is the unmodified testset class from MUnit (full code attached) which
takes a vararg as input.
