Problem with horizontal beams

[James Lowe]

Hello,

There seems to be an inconsistency with setting horizontal beams.

We have a snippet where we state that

\override Beam #'damping = #+inf.0

Should generate horizontal beams in all cases.

However the simple example attached shows some odd inconsistencies.

All the notes are identical per measure but the horizontal beams are not.

In the second group the only difference is that I added some manual breaks
after each measure  - but you get more inconsistencies.

A PDF is probably too big to attach and the PNG shows you the anomoly, but
not the weird distribution of these non-horizontal beams.

Is this a bug?

Thanks

James
