+#  All existing line endings must be identical (e.g. lf's only, or even
+#  the accedental cr.cr.lf sequence.)  If some lines end lf, and others as
+#  cr.lf, the file is presumed binary.  If the cr character appears anywhere
+#  except prefixed to an lf, the file is presumed binary.  If there is no 
+#  change in the resulting file size, or the file is binary, the conversion 
+#  is discarded.
