Well observed!
I think it was added in 251.1022 (Jan 2010).
It has been in my Dutch language file also since the 1022-build.
But it indeed isn't mentioned in the most recent lang_changes.txt files (any more?).
Maybe it never was?

Edit 29-Mar:
As a lot of issues mentioned in this thread were "repaired" from the time I first started it, I decided to make a new post with only the remaining issues.
This is the newer edition:

In this connection this 'old' thread is hereby closed.
