Martin,
1. I'd vote for replacement.
2. The "Sig" argument was completely opaque to me. I'd vote for something
like this
bracket = "fixed" the old behavior, treat the upper and lower as fixed
values
= "search" expand the limits if needed
= "usearch" only the upper limit is expanded
= 'lsearch' only the lower
3. I agree with Duncan that the searches should count toward the total
iterations.
