Duncan filed a bug report via R bugzilla (thanks).

There is no way to disable this functionality and it has existed for
very long time, I tested that at least in R 3.0. Optionally ending the
session was I believe intentional with Ctrl+D, when the input is empty,
and it is also how Unix terminals work. But ending the session with DEL
was probably an implementation compromise and I've changed that in
R-devel. Thanks for the report.

More implementation details in the bugzilla report:

Best
Tomas
