Playing with bound-padding, it looks like bound-padding has the
unfortunate effect of creating a gap at the *left* end of the trill
spanner (opening up space between the "tr" and the beginning of the
trill line) rather than at the *right* end (which is where the
whitespace needs to open up instead).
%%% BEGIN BOUND PADDING %%%
\version "2.11.7"
\new Staff {
\once \override TrillSpanner #'bound-padding = #4
\once \override TrillSpanner #'extra-offset = #'(-4 . 0)
c'4 \startTrillSpan
c'4 \stopTrillSpan \startTrillSpan
c'4 \stopTrillSpan
c'4
}
%%% END %%%
Beginning in 2.11.14 there is now an explicit solution to this problem
of shortening left or right ends of spanners precisely.
The property in question is bound-details and many of the different
spanner grobs (such as TrillSpanner, TextSpanner and Glissando)
implement it.
%%% BEGIN BOUND-PADDING EX %%%
\version "2.11.14"
\new Staff {
\override TrillSpanner #'bound-details #'right #'padding = #2
c'4 \startTrillSpan
\revert TrillSpanner #'bound-details #'right
c'4 \stopTrillSpan \startTrillSpan
c'4 \stopTrillSpan
c'4
}
%%% END %%%
This puts an end to the need to use the multiplication-scaled skip
hack to shorten the right end of hairpins and the like.
(Note also four arguments to override instead of the usual three.)
Some other example bound-details subproperties appear in the 2.11 NEWS file.
