[Dune-devel] Request for late release feature

[Oliver Sander]

Dear 2.3 release managers,
I know we are late in the release process.  Nevertheless I would like to ask
for the following patch to be cherry-picked to the dune-istl 2.3 release branch,
even though it is not a bugfix.  It is very non-invasive though, only adding
one method.  Having this method in the release would help me greatly.
Thank you very much,
Oliver
