The function does this:

         for FILE in "$expect" "$actual"
         do
                 grep -v "IN: clean" "$FILE" >"$FILE.tmp" &&
                 mv "$FILE.tmp" "$FILE"
         done &&

It is an interesting case: If only matching lines are in the file, 
nothing would be printed, and grep returns failure. But we shouldn't 
care, because, strictly speaking, the function only wants to remove 
lines with a certain pattern. Here, it actually hurts to &&-chain grep!

It wouldn't hurt to write 'mv ... || return', but at the same time, && 
after grep should be removed.
