I'll bet there's a lot less of a problem with starting up and shutting down diesels cold vs. gasoline engines, especially when carburetors were still in use. A cold engine is a good way to get condensation of gasoline material and having it run down the cylinder walls such that the next start is a dry start. Whereas, any excess diesel fuel is less of a problem because it'll actually do a bit of lubrication.
Doubt this shutdown cold thing is much of a problem now with fuel injection in gasoline engines. There's no excess fuel around to condense. Of course, all diesels have been injected.
