[NTG-context] spacing between chapters in TOC

[jbf]

Hi list,

I want my table of contents to look like:

Chapter             1
     section           5
     section          10
     section          15

In other words with section items indented.

I presumed I would need to do something with \setuplist[section]. I know 
how to control interline distance, whitespace, but in this instance, not 
indentation of certain lines in a toc. I tried 
\setuplist[section][indenting=yes] and even indentation=yes in the hope 
that existed. It doesn't, at least not used this way.

But it must be simple enough to achieve?
