> As can be seen, luatex ignores `@allowcodebreaks false`. More diagnostic: For this input file
```
\input ltluatex
\input nodetree
\NodetreeSetOption[verbosity]{3}
\NodetreeRegisterCallback{postline}
\input texinfo
@allowcodebreaks false
@code{foo-bar}
@bye
```
'nodetree' shows the attached image. If I comment out the
`@allowcodebreaks` line, I get exactly the same. In other words,
`@allowcodebreaks` doesn't have any effect if luatex gets used.
