One could make that an implementation proviso, namely that scanning has
to start at $1 and will forcibly be terminated at $N where $N is the
largest consecutive counter. Sounds like a small sacrifice for what
strikes me as a useful option. In most instances, this would suffice
and the proviso is unlikely to bite a careful or sensible programmer.
One might also want to allow for a "skip" field along the lines of
scanf()'s %* to assist where arguments must legitimately be left out.
Sounds a bit of a botch, but it would serve some purpose.
