I think the best wasy to reliably track a project is to run the scrpts
in BATCH, rather than interactively -- you may think you've got a record
of everything you did interactively, but how can yo ube sure?

I first noticed it probably 8-9 years ago (!), and I tried (and failed)
then to debug the cause, so it was not trivial then, and I doubt
trivival now.  My hunch would be that it was something that changed in
comint.el rather than the ESS sources.
