well, I clearly agree with the first part...

Well, actually, it does .. a bit later... and every time you
print, from then on.
But you are right: R should alert the user more clearly!
I propose to implement that it will produce an *error*, if the
result is not a positive integer.
Another question: Would anyone (on R-core ?)
know why we print two closing "]]" but only one initial "["
in the following ?
[ reached getOption("max.print") -- omitted 19800 rows ]]
If nobody sees a good reason for the above asymmetry,
I'll change it to something symmetric, i.e., matching pair,
and would propose to use the more rare pair
"{{" .. "}}"
