Revision 5ec147bf5f5edfb6304f5793d47d16564cf63ba9 authored by Milan Bouchet-Valat on 12 January 2018, 21:29:19 UTC, committed by Milan Bouchet-Valat on 13 January 2018, 18:09:22 UTC
The BitArray method was missed when changing the AbstractArray method to return CartesianIndices for multidimensional arrays. Also fix the find(x) docstring which was inconsistent with the find(f, x) one.
