I assume they will just be adding more output for other node types
(read "add" as an abbreviation for "additionally, produce information
for .."). The point of this patch, iiuc, is that there is no need for
node list manupilations.

It would be interesting to have the full precision as an option.
A macro package for two-pass page break optimization may want to
use the synctex file also , and such a package would really need
full precision to avoid rounding errors.
