actually a rather old bug, but that it surfaces now is a side effect of 
some experimental optimzxiation that makes us end up in another injector

[NTG-context] No kerning across discretionary nodes in latest ConTeXt upload

[Marcel Fabian Krüger]

Hi,

since the latest upload, ConTeXt no longer applies kerning across
discretionary nodes:

\starttext
\setbox0\hbox{V\-a}
\showboxdepth\maxdimen
\showboxbreadth\maxdimen
\tracingonline1
\showbox0
\stoptext

used to show

> \box0=
\hbox(8.1915+0.25186)x13.69647, direction TLT
.<1: lmroman12-regular @ 12.0pt> V
.\discretionary (penalty 50)
..< <1: lmroman12-regular @ 12.0pt> -
..= \kern-0.98346 (font)
.<1: lmroman12-regular @ 12.0pt> a

but now changed to

> \box0=
\hbox(8.1915+0.25186)x14.67993, direction TLT
.<1: lmroman12-regular @ 12.0pt> V
.\discretionary (penalty 50)
..< <1: lmroman12-regular @ 12.0pt> -
.<1: lmroman12-regular @ 12.0pt> a

This seems like a regression.

Best regards,
Marcel
