2.1.6 - wierd polyphony output |

On Lilypond 2.1.16 (self compiled). Originally noticed on 2.0.1
Not sure whether these are interrelated or should be reported
separately. The attached .ly and .pdf/.dvi) are the original test
case(s). Hopefully I've put in slightly more concise test cases in line
here.
1: Chorded polyphony with dotted notes in voice 1 misplaces dots (as
shown in attached output bar 7)
\score {
\notes \relative c'' {
time 4/4 r1
<< { <a c>2 s4 } \\ { <b d>4. <b e>4. } >> r4
}
\paper {}
}
2: Collision avoidance is different in non-chorded vs chorded polyphony
( shown in bars (6 vs 7) compared to (9 vs 10)). I believe the chord
case should use the same decision as the single-note case.
\score {
\notes \relative c'' {
time 4/4 r1
<< { a2 s4 } \\ { b4 c d } >> r4
<< { <a c>2 s4 } \\ { <b d>4. <b e>4. } >> r4 \break
% same notes, switch voices
<< { b4 c d } \\ { a2 s4 } >> r4
<< { <b d>4. <b e>4. } \\ { <a c>2 s4 } >> r4
}
\paper {}
}
3: Starting a score with polyphony seems to generate unnecessary new
contexts. (I discovererd this while eliminating the 'r1' at the
beginning of each system, trying to simplify the test cases - not
bothering me, but I thought I'd better report it.)
remove the 'r1' after 4/4 from either of the above.
Thanks
