I guess you tested this in the *scratch* buffer, whereas I tested it in
a fundamental-mode buffer.

In *scratch* point seems indeed to be stuck on the "d" of "dummy" while
in fundamental-mode the behaviour is like I described it above.

However, fd93edb from 2015-03-27 behaves in the same way as trunk does,
in *scratch*, too.
