Thanks for reporting the problem.  This thread chronicles a previous
discussion concerning the problem you reported.  It is apparently
fixed in the current CVS and testing version diffutils-2.8.7.  The
next release will include a fix for this problem.


I think this might be the change that fixed it.  It is in the area.


Unfortunately there are no plans for a new diffutils release anytime
soon.  So there is no way to predict when a fix would get released.


I suggest getting the current alpha test version and verifying that it
is operating correctly for you in your environment.  Please report any
problems found as that version is the current development track.
