For interested, you can check:

for patch.

It works fine and should be almost ready for commiting. Just one
unnecessary "if" and some spaces and line end.

I'll wait a day for comments/objections.

Still the question is commiting this to 4.3. It adds feature, so
should not be commited. On the other hand it's quite important feature
missing.
