I am applying it incorrectly, or it does not work with the buffers created by \grabbufferdata:

\setupwhitespace[none]
\setupindenting[none]
\starttexdefinition unexpanded startBufTest
  \bgroup
  \dosingleempty\dostartBufTest
\stoptexdefinition
\starttexdefinition dostartBufTest [#SETUPS]
  \getrawparameters[BufTest][xx=yy,#SETUPS]
  \grabbufferdata[TestBuffer][startBufTest][stopBufTest]
\stoptexdefinition
\starttexdefinition stopBufTest
  \startnarrower[left,right]
  \startparagraph
    \BeforePar{\dontleavehmode\llap{? }}\GotoPar
    \inlinebuffer[TestBuffer]
  \stopparagraph
  \stopnarrower
  \egroup
\stoptexdefinition

\starttexdefinition stopBufTest
  \startnarrower[left,right]
  \startparagraph
    \dontleavehmode\llap{? }%
    \blank[overlay]
    \inlinebuffer[TestBuffer]
  \stopparagraph
  \stopnarrower
  \egroup
\stoptexdefinition

Thank you, Wolfgang. That does it. Note that the % escaping the line end is not needed (    although it might be needed outside a \starttexdefinition environment) – the following works as well:

\starttexdefinition stopBufTest

  \startnarrower[left,right]

  \startparagraph

    \dontleavehmode{\llap{? }}

    \blank[overlay]

    \inlinebuffer[TestBuffer]

  \stopparagraph

  \stopnarrower

  \egroup

\stoptexdefinition
