This _is_ a Hennigian comb, because in a cladogram, _only_ topology counts.
A cladogram is a mobile. Look at the following -- it's exactly the same
cladogram as above:
--+--F
`--+--A
`--+--E
`--+--B
`--+--D
`--C
... what a side branch is lies completely in the hand of the presentator.
All I did was I rotated a few stems around their long axes.
