Trouble with paragraph duplication

Hi all,

I'm having  a little bit of trouble understanding some Lout behavior.
I'd like to be able to replicate a paragraph programmatically, so that
it can be placed in a document several times. I've noticed that Lout
deletes everything if I put any paragraph control characters in my
paragraph text. Why is this?

As an example, this works:

    @SysInclude{ doc }

    def @Lorem{
    Lorem ipsum dolor sit amet, consectetur adipisicing elit, sed do
eiusmod tempor
    incididunt ut labore et dolore magna  aliqua. Ut enim ad minim veniam, quis
    nostrud exercitation  ullamco laboris nisi ut aliquip ex ea
commodo consequat.
    Duis aute irure dolor in reprehenderit in voluptate velit esse cillum dolore
    eu fugiat nulla pariatur. Excepteur sint occaecat cupidatat non
proident, sunt in
    culpa qui officia deserunt mollit anim id est laborum.
    }

    @Document

    @Text @Begin
    @PP
    @PP
    @Lorem
    @PP
    @PP
    @Lorem
    @End @Text

But this doesn't:

    @SysInclude{ doc }

    def @Lorem{
    @PP
    @PP
    Lorem ipsum dolor sit amet, consectetur adipisicing elit, sed do
eiusmod tempor
    incididunt ut labore et dolore magna  aliqua. Ut enim ad minim veniam, quis
    nostrud exercitation  ullamco laboris nisi ut aliquip ex ea
commodo consequat.
    Duis aute irure dolor in reprehenderit in voluptate velit esse cillum dolore
    eu fugiat nulla pariatur. Excepteur sint occaecat cupidatat non
proident, sunt in
    culpa qui officia deserunt mollit anim id est laborum.
    }

    @Document

    @Text @Begin
    @Lorem
    @Lorem
    @End @Text

Any thoughts as to what might be causing this?

Thanks,
Nick
