Hi!

Make a file (test.txt) containing :

        3
        33
        333
        3333


Then do a :

        cat test.txt | grep -w 3


On 4.0F patchkit 4 and 4.0D patchkit something, grep returns all lines.
On 5.1 patchkit 3 grep returns only the first line. The same happens on
Solaris 7.

I believe grep -w in 5.1 and Solaris 7 is behaving correct according to the
man description, and wrong on 4.x.


Fixed in any patch, or ?
