[NTG-context] redefining paragraph breaks

I know I could do it manually, but that makes the source ugly, so is there a way to redefine paragraph breaks so that instead of actual breaks in the output they are kept as running text separate by a paragraph symbol, e.g.: This is paragraph 1. This is paragraph 2. Becomes in the typeset document: This is paragraph 1. ¶ This is paragraph 2. ? c -- Chris Lott
