It marks references, and if it is already marked, also all objects used by this
reference are already marked, so in case of pdfseparate and pdfunite You can
break immediately (>1). But I use this functionality also in other cases, i.e.
when removing spot colors from a PDF. In this case I also to remove remove the
spot colorspace objects from the PDF if no more referenced, and in this case I
need the counter. (If I'll get some time in future and poppler community is
interested, I could also add this tool, removing and / or replacing spot
colors, but I think this is a more or less scientific use, and not a lot people
are really interested in such a feature)
