Encouraging use of "send-email" with "--patience" is a losing
approach if your goal is to present more reviewable diff, isn't it?
Using "send-email" as if it is a front-end of "format-patch" means
you lose the opportunity for the final proof-reading (not just
finding typoes in the message, but the shape of diff, like you are
pointing out).

Using "format-patch --patience" or some other diff option, and pick
the best one to give to "send-email" would indeed be a way to do so.

I wondered if this is an example of real-world fallout from
0018da1^2~1 (xdiff: implement empty line chunk heuristic,
2016-04-19), but it does not seem to be so.

What is happening is that Antoine's patch (which is slightly
different from what you quoted above) has trailing whitespace after
"setup_path();", so it indeed is the original setup_path(); is
removed, a few lines were inserted, argv[i] reference is removed
and then a totally different "setup_path();     " was added there.

With that whitespace-breakage corrected, the resulting patch ends
more like this:

+       if (argc != 1)
+               usage_with_options(upload_pack_usage, options);
 
-       if (i != argc-1)
-               usage(upload_pack_usage);
+       if (timeout)
+               daemon_mode = 1;
 
        setup_path();
 
-       dir = argv[i];
-
+       dir = argv[0];
        if (!enter_repo(dir, strict))
                die("'%s' does not appear to be a git repository", dir);
 
which is more reasonable.

So in the end, this was not "Not a problem with your code" ;-) It
was.
