Re: bug in echo command

   the echo command doesn't read string sequences such as \c or \r
   even when the option -E is not used. for example:
    echo "Today is \c "
   produces
    Today is c
   on the screen.

>From the manual, (coreutils) echo invocation:

`-e'
     Enable interpretation of the following backslash-escaped
     characters in each STRING:

    `\a'
          alert (bell)

    `\b'
          backspace

    `\c'
          suppress trailing newline

    `\f'
          form feed

    `\n'
          new line

    `\r'
          carriage return

    `\t'
          horizontal tab

    `\v'
          vertical tab

    `\\'
          backslash

    `\NNN'
          the character whose ASCII code is NNN (octal); if NNN is not
          a valid octal number, it is printed literally.
