ConTeXters,

I am stymied trying to insert characters into a buffer, or failing that, to back up, removing the \par, and adding characters after the buffer is loaded.

The code I am working with reduces to this:

1. % macros=mkvi engine=luajittex
2. \starttexdefinition unexpanded startABC
3.   \begingroup
4.   \dosingleempty\dostartABC
5. \stoptexdefinition
6. \starttexdefinition dostartABC [#SETUPS]
7.     \getrawparameters[ABC][inset=2em,#SETUPS]
8.     \grabbufferdata[bu:ABC][startABC][stopABC]
9. \stoptexdefinition
10. \starttexdefinition stopABC
11.     \setupnarrower[left=\ABCinset]
12.     \startnarrower[left,right]
13.       \startlines
14.         (\,\inlinebuffer[bu:ABC]\,)
15.       \stoplines
16.     \stopnarrower
17.   \endgroup
18. \stoptexdefinition
19. \starttext
20. \startsubject[title={Test of ABC}]
21. \startABC[inset=5em]
22.   “Hope” is the thing with feathers\,—
23.    That perches in the soul\,—
24.    And sings the tune without the words\,—
25.    And never stops\,—\,at all\,—
26. \stopABC
27. \startABC
28. ABCDEFG
29. \stopABC
    
30. \stoptext

In line 14, I prefix the buffer with (\, but \,) ends up on another line, after the \par inserted at the end of the buffer. Inlining a second buffer which contains the closing  bits with (\inlinebuffer[a,b]) does the same.

Can somebody suggest a path?
