But so many people now use -u format that the next POSIX revision will specify it. The draft POSIX specification for -u says that "diff -u" format can use an empty line instead of a line with a single space. This was in response to Jim's concern. So we need to change Diff mode, even though I asked them to revert the change in GNU Diff. Would someone please make that change in Diff mode, then ack?
