Now I see that the user-level nzmax function calls capacity if it is
given a sparse matrix object, and has this comment:

      // XXX FIXME XXX should nnz be a method of octave_base_value
      // so that the below can be replaced with "retval = (double)
      // (args(0).nz ());"

(this is referring to the original nnz function).  So maybe it would
be better to use the name nzmax instead of capacity.  Unless you
object, I will make that change, and add nzmax to the octave_value
