Actually, I think it is best to use boolean indexing.  Find introduces
another function call to slow things down and in Octave, only works
with vectors unless do_fortran_indexing is nonzero (which introduces
another set of problems).

The original ambiguity was stupidly copied from Matlab, and
prefer_zero_one_indexing was naively introduced in an attempt to solve
that problem.  Logical matrices and indexing avoids the problem, so
prefer_zero_one_indexing is no longer needed in Octave 2.1.x.
