I think before you can recommend wdiff,
  1) there should be a release on ftp.gnu.org that does not dump core at
     every invocation, (*)
  2) the program should support colorized output like we know it from webcvs
     and others.

(*) Yes I know there is a release wdiff-0.5.90 that works better than that,
    but it's not on ftp.gnu.org.
