Bug#2312: Silly message from diff about fifos
I'm closing this bug report again. The program is working as designed.
In particular, the program considers it an error to do a diff operation
on named pipes (fifos). To me, this seems reasonable.
If you have a disagreement with the authors regarding this aspect of
their design, please take it up with them. The upstream bug report
address is firstname.lastname@example.org.
