Collision between note beams and chords using tabFullNotation

[Mark Brophy]

> I'm not top posting.

% This bug is a "tiny example" because nothing can be removed; the bug 
% is a consequence of a dense set of eighth and sixteenth notes placed 
% in guitar tablature using tabFullNotation.
% The bug causes a collision between the beams of the notes and chords 
% above in the second line; there are no collisions in the first line.

\version "2.14.0"  % necessary for upgrading to future LilyPond versions.
