the magic?
patch(1) was written by Larry Wall in 1985, and released over Usenet.
v7 users likely used diff -e, and piped to ed to apply it.
That makes sense. So, if that's how it went then I'm wondering if my
diff is meant to run against source on the host and the results placed
into v7, rather than run in v7. Does this look like a modern diff vs the
old stuff?:
