I confirm this.  What's worse, it is true back through
Emacs 24.5.  Emacs 24 seems to be where this regression
was introduced - in Emacs 23.4 there is no such problem.

The recipe I used was to insert two subdirs of a dir D,
and then to insert a subdir of one of those subdirs.

When I did the latter action, the second subdir of D
that I inserted was shifted right.

Debugging with `emacs -Q' just a bit, the problem seems
to be in `dired-insert-directory', when it does this:

(indent-rigidly opoint (point) 2)

The problem is that (point) is past the end of the
subdir that is being inserted.  It's past the end of
the next subdir, so that one gets indented also.
