The request for this feature and a lenghty discussion about the best way
to implement it is already "pending" in the core list.

Search for RFC #10011. Started out simple but got more and more opinions
and complexity added, so that at the end there was no output at all from
the effort. Shame, could have been in 4.5.

If you want to try again, I suggest to open an new thread for it in the
core list, maybe even take the last patch from Franz and work upon that.
Maybe trying to sum up the opinions and what leaded to this particular
patch and pointing to the previous discussion.

Cheers,
Ernesto
