Thanks for the pointer.

Nevertheless, the bug report was filed because I think that the -R
option would save the user typing. Compare:

  cp file{,.orig} && diff -R file*


  cp file{,.orig} && diff file{.orig,}


  cp file{,.orig} && diff file* | interdiff - /dev/null

To me, making life easier for the user by introducing a feature
that's not too far from the diff core application seems like the way
to go, especially with free software, especially because it can
hardly be considered bloat. I am not asking anyone to make diff play

Please do not send copies of list mail to me; I read the list!
