Hi, it's been ages that I actually wanted to produce a "classic" diff, and I don't think I'm alone in that. Yet, I still have to remember to add `-u` every time I invoke `diff`.
I understand changing the default is controversial. But perhaps even using "classic" as default unless POSIXLY_CORRECT is set. But we should be able to support a GNU_DIFF_FORMAT environment variable that sets the default format, no? I could send a patch, but first want to understand if that would have any chance of being applied. </nk> P.S.: I know I could write my own little wrapper script/alias/shell function, but that all seems dirty in one way or another. --nk
