Thanks for the suggestion - I was actually aware of the use of \shape to adjust
the slur, but hadn't implemented it since I thought it more sensible (perhaps
naively) to get all the notes in place and then adjust the slurs at the end of
the process.
However, for me introducing this doesn't fix the problem. I still get the same
error when I use the following code:
\version "2.18.2"
\include "definitions.ily"
\language "english"
\layout {
\context {
\Staff
\override VerticalAxisGroup #'default-staff-staff-spacing =
#'((padding . 4))
}
}
music = {
\set restrainOpenStrings = ##t
\set TabStaff.minimumFret = #12
\relative a' {
r2 c16 ( \glissando b )
\bendOn \bendGrace g' ( a8 ) ( \bendGrace g ) ( a ) \bendGrace g ( a ) |
\bendGrace g ( a4 ) \bendGrace \preBendHold g ( a16 ) ( g8 )
\bendGrace g ( \holdBend a16 ) ~ a8 ( g16 ) e
d ( e ) g \bendGrace \preBendHold d ( e ) ( |

And this is a full example of the workaround. I might add it to the README on
Github:
\version "2.18.0"
\include "notation-snippets/guitar-string-bending/definitions.ily"
music = \relative c' {
\set TabStaff.minimumFret = 4
\set TabStaff.restrainOpenStrings = ##t
\bendOn
fis8( g)( fis) \bendOff
\shape #'((-0.8 . 0.5) (-0.8 . 0.5) (-0.8 . 0.5) (-0.8 . 1)) Voice.Slur
\shape #'((-0.5 . 0) (-0.5 . 0) (-0.5 . 0) (-0.5 . 0.3)) TabVoice.Slur
\hideNotes \grace fis( \unHideNotes e)
}
\score {
\new StaffGroup <<
\new Staff { \new Voice { \clef "treble_8" \music } }
\new TabStaff { \new TabVoice { \clef "moderntab" \music } }
>>
\layout {
indent = #0
\context { \StaffGroup \override StaffGrouper.staff-staff-spacing.padding =
#3 }
}
