+FIXME: Add owner of second tree to To:

+Today's linux-next merge of the BRANCH tree got $conf in:
+
+$files
+between commit$hcs:
+
+$(printf '  %s\n' "${hc[@]}")
+
+from the ${hb[*]} tree$hbs and commit$mcs:
+
+$(printf '  %s\n' "${mc[@]}")
+
+from the BRANCH tree.
+
+I fixed it up (see below) and can carry the fix as necessary. This
+is now fixed as far as linux-next is concerned, but any non trivial
+conflicts should be mentioned to your upstream maintainer when your tree
+is submitted for merging.  You may also want to consider cooperating
+with the maintainer of the conflicting tree to minimise any particularly
+complex conflicts.
