"Afterwards" is in dired-insert-directory? As said, this is not always
in play.

Don't know whether it causes major problems. I guess the cases in core
Emacs can be fixed easily. For possible other implementations in the
wild, I don't know.

I do not oppose heavily to this change. The advantage is, that the
boring "adjust the free disk space" must not be implemented again and
again in all insert-directory incarnations. But a coordinated change
would have been better ...

Well, what about this change in etc/NEWS:

diff --git a/etc/NEWS b/etc/NEWS
index d783fc019c..304f707f2e 100644
--- a/etc/NEWS

And I will see what must be done in Tramp and ange-ftp.el
