+      If entries are entered in plain text mode, the browser adds automatically a
+      CRLF at the end of each line where the text wraps. This ensures that the submitted
+      entry has the same line breaks as in the edit box. If this behaviour is not
+      wanted, the adding of hard wraps can be turned off by setting this value to <b>0</b>.
+      If the user then enters a very long line without hitting the newline key,
+      the long line is preserved which can make it hard to read.
