[NTG-context] line wrap marker

We have lines of text that shouldn't be wrapped. If one line must be wrapped onto the next, we'd like to insert a visual mark at the end of the line and (hopefully) indent the next line slightly. Obviously, there's the potential for wrapping over multiple lines. I've dug around TeX, LaTeX and ConTeXt, and none appear to support this yet. So far, ConTeXt has been the most enjoyable to work with, so I'm okay with a ConTeXt only answer. How hard will this be to implement? Where should I start looking to figure out how to do this? I'm hoping for an answer along the lines of "this set of macros will probably be helpful". -- Stuart Jansen Guru Labs, L.C.
