Hello Jakob,
try to do something like this:
\tweak extra-spacing-width #'(-1.5 . 0) a'
this will tell Lilypond to add 1.5 spaces to the left of the stem for spacing.
In this case this will work out, but say if the d and the f# the beat before
were an octave higher there would be no collision, so Lilypond won’t apply
this width. In this case one might need to do
\tweak extra-spacing-height #'(-inf.0 . +inf.0)
\tweak extra-spacing-width #'(-1.5 . 0) a'
which tells Lilypond to handle that Stem as if it was infinitely long in both
directions (up and down).
But keep in mind that Lilypond does not really require this tweak as much as
the original, as it aligns the Voice follower line centered on the Stem. See
for yourself:

Greetings!
I'm attempting to move a note horizontally to fix a poorly placed
voice-leading line.
Breitkopf fixes it by nudging the a following the staff change to the
right, and I'd like to copy that.
A minimal example from my score:
\version "2.24.1"
\language "deutsch"
global = {
\key g \major
\time 4/4
\showStaffSwitch
\override VoiceFollower.style = #'dashed-line
}
rightOne = \relative c'' {
\global \voiceOne h4 h a g | fis!2 f'~ | f4 f e d |
}
rightTwo = \relative c'' {
\global \voiceTwo g4 f e2 | \voiceThree d2 d'~ | d h |
}
leftOne = \relative c' {
\global \voiceOne e4 d c h |
a \change Staff = "right" \voiceTwo \once \override
NoteColumn.force-hshift = #3 a' gis a | h2 e, |
}
leftTwo = \relative c' {
\global \voiceTwo e,2 a | d,2. c4 | h2 h' |
}
pedal = \relative c {
\global c1~ | c4 c h a | gis2 gis' |
}
\score {
<<
\new PianoStaff <<
\new Staff = "right" << \rightOne \\ \rightTwo >>
\new Staff = "left" { \clef bass << \leftOne \\ \leftTwo >> }
>>
\new Staff = "pedal"
<< \clef bass \pedal >>
>>
\layout { ragged-first = ##f }
}
I've included a couple of extra bars because I wasn't sure if it was
related to something in those.
\once \override NoteColumn.force-hshift = #3 doesn't seem to work. (3
was just an arbitrary number to see if it would move.) I can nudge the
notes at the beginning of the bar to the left, except the force-hshift
fails to work on the tied d in the bass line.
I'm sure there's a simple explanation, but I've been unable to figure it
out so far.
Best wishes,
Jakob Pedersen
