+The following patch works around the bug in grep which makes
+
+       grep '[a-c]'
+
+match "B".  Note, this is a bug in grep caused by a bug in the
+standards which do not provide interfaces to get the necessary
+information.  This patch as correct as grep was before (multibyte char
+handling is not 100% correct but that cannot be solved now), future
+changes might increase the speed a bit.
