Hi Risto,

(One of) the settings you seek is ...

   \override TextSpanner #'bound-details #'left #'stencil-align-dir-y = #CENTER

... which you can, for example, include in your definition of
trflatstartI. Like this:


%%%%%%%% New snippet %%%%%%%%%%%%%
\version "2.11.34"

trstyle = {
  \override TextSpanner   #'style = #'trill
  \override TextSpanner   #'edge-height = #'(0 . 1)
}

trflatstartI = {
   \trstyle
   \override TextSpanner #'bound-details #'left #'stencil-align-dir-y = #CENTER
   \override TextSpanner #'bound-details #'left #'text =
       \markup{\musicglyph #"scripts.trill"
       \raise #1.0 \smaller \flat}
}

trflatstartII = {
   \trstyle
   \override TextSpanner #'bound-details #'left #'text =
       \markup{ \column{\tiny\smaller\smaller\smaller{\flat}
           {\musicglyph #"scripts.trill"}}}
}

one = \relative c' {
   f2.. \startTrillSpan f8 \stopTrillSpan |
   \trflatstartI f2..^\startTextSpan f8 \stopTextSpan |
}

\new Staff {
   <<
   \one
   >>
}

%%%%%%%%% END %%%%%%%%%%%%%



Other goodies like this can be found under 8.1.2 "Trill and line
spanners" in the 2.11 version of the manual.

As far as #'to-barline = ##t ... I think that that *was*, in fact,
supposed to work in precisely this case, so that may be a bug; but
I'll have to run a few more testfiles first.

And, as a sidenote, the layered voices technique you're using is
pretty common tool for many of us on the list; even though it looks
like a pain when you first stumble upon it, the technique works
surprisingly well. Two notes, though: skips like s4 do behave
differently that (invisible) notes and rests for spacing purposes, as
you're discovering; that's perfectly normal (but I think there may be
a PaperColumn override to make skips behave the same way in the
spacing problem; again I need to check). Also, you can get rid of the
clashing note columns (which are quite common when you use hidden
voices) with the incantation ...

   \override NoteColumn #'ignore-collision = ##t

... which you can either set globally for an entire voice or score (or
call selectively).

I haven't adjusted the y alignment on trflatstartII; if you figure it
out could you post back to the list?
