What are warning signs for a worn-about-to-snap timing chain on a 1983 or '85 W123 turbodiesel?

If the oil changes haven't been overextended, it's unlikely IMO that the chain would be in need of replacement at only 150K miles. Use of a diesel-rated synthetic such as M1 "Turbo Diesel Truck" a/k/a Delvac-1 should reduce chain wear/stretch to nearly negligible. Check it as Mitch described if you want to put your mind at ease. The rough starts could be due to a bad glow plug or two... is your dash glow lamp working properly? This will only get worse as the fall/winter arrives and temps start to drop.
