Details:

For example:


octave:1> hist ([ 1 1 ])
error: bar: X vector values must be unique
error: called from
    __bar__ at line 62 column 9
    bar at line 118 column 16
    hist at line 192 column 5


MATLAB is able to deal with this case correctly, and creates bins with a unit
space between them.

I will attach a patch in the next comment (I need the bug number for the
commit message).
