Summary:                    troubles with grep and pipe when \n char is not sent
Description: 
Hi all
when i make a command like this

echo -n "hello world" | grep hello

i obtain an empty string while when i send:

echo "hello world" | grep hello 

i obtain      hello world.
Problem seems caused by \n char present at the end of the string; non
present both in older versions and bash you can find in all linux
distros.
bye

No. See different:

$ echo -n "hello world" | ./busybox grep hello 
hello
$ echo -n "hello world" | ./busybox grep world 

A patch attached.
