>Description:

        do this:

        % (echo foo; echo bar; echo baz) | less

        search for "foo" by typing /foo
        notice that while it highlights foo, it also says "Pattern not found"
        notice that this happens only for text found only on the first line.

>How-To-Repeat:

        as above

>Fix:
