Proposed resolution:
Recommend NAD.
[ Batavia (2009-05): ]
Pete to provide "straightforward" wording. Move to NAD Editorial.

I'm not happy with NAD if we can find a simple solution.
How about adding a rider somewhere in clause 17 suggesting that complexities that specify a negative number of operations are treated as specifying zero operations? That should generically solve the issue without looking for further cases.

Suggest NAD. The complexity of empty ranges is -1 in other places in the standard. See [alg.merge] merge and inplace_merge, and forward_list merge, for example. The time and effort to find and fix all places in the standard where empty range[s] result in negative complexity isn't worth the very limited benefit.
In [includes] the complexity is "at most -1 comparisons" if passed two empty ranges. I don't know how to perform a negative number of comparisions!
