fingering layout bugs

[Edward Sanford Sutton, III]

Here's a sample of expressing a few issues I've noticed with fingerings (and 
no, its not my poor choice of #s for my made up fingerings that I'm trying to 
express): 
\version "2.1.30"
fingeringLeft = { \once \set fingeringOrientations = #'(left) }
fingeringRight = { \once \set fingeringOrientations = #'(right) }
\score {
\notes\relative c'' {
\fingeringLeft <c-2 d-3 f-4> \fingeringRight <c-2 d-3 f-4>
% fingering intervalic seconds collide when placed on sides
s
<c, d e g'>8_2_1-3-5 % chord attached avoids beams, but do not follow notes
<c-1 d-2 e-3 g'-5>8 % note attacked fingerings do not avoid beams

<c'-1 e-3 g-5>
\fingeringLeft <c-1 e-3 g-5>
% tight (but default) spacing places fingerings closer to adjacent chord
\fingeringRight <c-1 e-3 g-5>
% tight (but default) spacing places fingerings closer to adjacent chord
<c-1 e-3 g-5>
\repeat unfold 50 {s}
}
}
