Sure, but the cost-per-byte of the strlen should be a good bit less than
the cost-per-byte of the actual conversion, so that doesn't bother me
too much.

Actually it seems like the hard part is not so much the input
representation as the output representation --- what should the
base-level initcap routine return, to be reasonably efficient for
both cases?
