As an idea for an optimization, if the block bsearch ends at the "min"
leg then there's no need to seek and read $min again to begin the linear
search -- the handle is already there.
This also has the happy effect of one less compare for end-at-min case.
For example the program duplicate-compare.pl below shows "513 cmp 514"
done twice, but just once after this change.
