RFR 8166051: [jline] Cannot parse .inputrc with \r

[Jan Lahoda]

Please review a change to how .inputrc is read. Currently, it uses 
BufferedReader.readLine(), which interprets '\r' as a line separator, 
and so the '\r' character cannot be used in the macros. The proposed 
change is to use System.getProperty("line.separator") and "\n" as line 
separators.
