I have been checking out a pre-release set of software (GNU) and which
uses a function in a shell script to determine whether or not the 'echo'
command
supports the '-e' flag (on FreeBSD it doesn't).

To cut a long story short try the following :-

   (echo -e) | sed s/-e/xe/ | grep xe; echo $?

here sed returns 'xe' and therefore should satisfy a match with 'grep' and
should return '0' but it returns a '1' (no match ?).

I think this is a 'bug' anyone agree ??
