Of these 4 macros, the last macro "nf-chunk-id" requires the quasi...unquote or I get the error "bad merge" if I try to invoke:

<nf-chunk-id|NAME|TAG|N>

I can't work out why. If I replace the call to nf-id with a call to another merge (as it used to be) then it works fine.

please help! 

These macros are part of a set to provide a fake-page environment which can be used when writing a document that talks about writing documents. It allows one to have a fake page or fake pages, with valid links and references between them, which under-go revisions within the narrative, but each revision gets it's own namespace.

The macros here are helpers for packages which will be fake-page -aware, so that they can prefix their id's with the fake-page namespace.

If found it much easier to do this when demonstrating literate programming than using render-only fake literate macros.

thanks
