skipTypesetting oddities

[Damian leGassick]

Hi all

1) in the following, the beaming goes wrong:

{
b8 b b b b b b b
\set Score.skipTypesetting = ##t
b b b b b b b b 
}

whereas if I skip one eighth later it's fine:

{
  b8 b b b b b b b
  b
  \set Score.skipTypesetting = ##t
  b b b b b b b b 
}


2) in this snippet of Beethoven, an extra tie or slur appears on the first two 
d16

{
  \set Score.skipTypesetting = ##t
  e'2~ e'8( d' cis' b) a2~ a8( a' g' e') 
  \set Score.skipTypesetting = ##f
  d'16\p d' d' d' d' d' d' d' d'8 r8 r4
}

if I move the skip##f back a note, it's fine:

{
  \set Score.skipTypesetting = ##t
  e'2~ e'8( d' cis' b) a2~ a8( a' g' 
  \set Score.skipTypesetting = ##f 
  e') 
  d'16\p d' d' d' d' d' d' d' d'8 r8 r4
}

any ideas how to get around this?

thanks
