This is surely related to https://savannah.gnu.org/bugs/?53603

With 4.2.2 and stable from a week or so ago (13fd0610480f+)


octave:17> find(false)
ans = [](0x0)
octave:18> find([false false])
ans = [](1x0)
octave:19> find([false; false])
ans = [](0x1)
octave:20> find([false false; false false])
ans = [](0x1)


But with 4.3.90 (hg id: 65f201566857+):


octave:48> find(false)
ans = [](0x1)
octave:49> find([false false])
ans = [](1x0)
octave:50> find([false; false])
ans = [](0x1)
octave:51> find([false false; false false])
ans = [](0x1)


I have not tested Matlab but because this caused a bunch of test failures in
the Symbolic pkg, I think 0x0 is the Matlab result.
