Some implementations of `echo` support the '-e' option to enable backslash interpretation of the following string. As an addition, they support '-E' to turn it off. However, none of these are portable, POSIX doesn't even mention them, and many implementations don't support them. A check for '-n' is already done in check-non-portable-shell.pl, extend it to cover '-n', '-e' or '-E'.
