Here's a scriptlet that will print the name of all the files for
which diff produces more than 5 lines of output.  (Which is not quite
to say that they differ in 5 lines, but it's close).

for file in $(find A -type f); do if test $(diff $file B/${file/A/} | wc 
-l) -gt 5; then echo $file; fi; done
