How to create proper horizontal offsets?

[Marten Visser]

Hi all,

Yesterday, I asked how a custom slur should be coded so that it gets 
transposed properly. This was answered immediately, thanks to David 
Nalesnik.

There's another related problem I run into when transposing scores, namely 
horizontal offsets. In songs this is encountered frequently because the 
stanzas may induce deviations from the rhythm.

In the example below one offset is changed when transposing. The log file 
shows a warning: 
warning: ignoring too many clashing note columns
        <<
          as'1 \new CueVoice = "SndStanza1" { \shiftNoteRight \stemDown 
as2. f8[ f] }>> |

When you leave out the \transpose commmand, this error will not appear.

How could the code be changed that horizontal offsets will always be there?

Thanks,
Marten Visser
