OK, thanks for pointing me in the right direction.  Revision 1.36 has
now been pulled up to the branch.  CHANGES-1.5.1 entry:

sys/kern/subr_extent.c                          1.36

  Fix calculation of whether we overflow the end of the extent.
  Fixes PR#13075.

I guess I'll go ahead and close the PR. ;-)
