The change was accidental (I forgot that R_ParseVector was in the API when I made it), but I think it will stay. Setting the value of this parameter to R_NilValue gets the old behaviour. Setting it to some other SEXP will have that SEXP recorded as the srcfile attribute of source references.

I think the description above is the level of detail of the implementation that it's safe to work with. The particular format of source references could change.
