I only skimmed the discussion, but how can we remove that?

I think freeing document memory has high potential to break things. 
There are a few places where Geany assumes document memory isn't freed 
over time.

If people don't like foreach_document (or Matt's improved C99 
foreach_doc with document pointers), we could add document_get_all or 
something that returned a list of valid pointers. That can be done 
without breaking existing code. Personally I prefer Matt's suggested 
macro because you don't have to free the list.
