Yes, there should and there will be one soon (see below).  But wdiff
as it appears in the packages on most GNU/Linux distributions (with
patches to fix these sorts of things) works quite well.  The 13+ years
since the release of wdiff 0.5 has provided ample time for these
patches to become stable.

By "the program", do you mean wdiff or some web-based diff viewer?  It
would seem strange for wdiff to provide colorized output since diff
doesn't even do that; colorized diffs are produced by other tools.
But if you can make a convincing case for colorized output in wdiff,
perhaps I could add it.  Though there are lots of other fixes for
wdiff's output that would take priority, such as providing context and
line/word numbers (like "diff -u").

wdiff 0.5.93 is now available (at http://alpha.gnu.org/gnu/wdiff/),
which includes a plethora of fixes since 0.5.90.  The plan is to
release 0.6 within the next month.
