From: Torsten Bögershausen <tboegi@xxxxxx>
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-'
