[Octave-bug-tracker] [bug #49944] histc is not compatible with Matlab when edges set is empty

[Avinoam Kalma]

Follow-up Comment #2, bug #49944 (project octave):

I have stumbled over this corner case while building and checking 
VLFeat <http://www.vlfeat.org/> library.

One of the tests, vl_test_whistc.m
<https://github.com/vlfeat/vlfeat/blob/master/toolbox/xtest/vl_test_whistc.m>
fails (in function test_no_edges()) because  
it expects to get Matlab histc results, and not errors.

Maybe Octave should output Matlab results, but with warning instead of error?
