Last night I tried to generate a diff between OpenBSD src "master" and
an updated "llvm15" branch.  Unfortunately, the output of "got diff"
would not apply to a checked-out src tree and I had to resort to git.

Some of the LLVM files have \r\n line endings.  The problem is that
got diff simply drops the \r from all context, - and + lines.

===> got diff | cat -v

Ironically, got preserves the \r for the function name line, but
git doesn't.
