Depending on the implementation, the echo command may
support options like -n -e -E or no options at all.
The only portable usage of echo is without any options,
which means that no parameter may start with a hyphen.
check-non-portable-shell.pl checks if echo -n is used.
Improve it to reject any parameter starting with a hyphen
and recommend the usage of printf instead
