- Prevents overly large ranges. A bug was reported from a user
who tried this:
% task annotate 1 1-987654321
The 1-987654321 was assumed to be a valid range, and caused task
to consume all available memory. The workaround was:
% task 1 annotate 1-987654321
But it seems a good idea to range-limit sequences. Currently
it is 1000. Perhaps this should be configurable.
