Some may have noted that R-devel, since svn revsion 65401 (= 2014-04-17 12:19:44 +0200)
now is patched, with log message

The daily (source!) snapshots of R devel now also contain it.

We plan to port the patch to 'R 3.1.0 patched' (to become 3.1.1
in the future) after the Easter holidays...
and would be glad if some volunteers could support development
of R by testing this (or newer) version of R-devel.
