Considering the following checked-in code:

int
main(int argc, char **argv)
{
        int a;

        return 0;
}

modified the following way:

int
main(int argc, char **argv)
{
        int c;
        int a;
        int d;
        int e;
        int f;

        return 0;
}

if you 'git add -p' on the file, you'll get:

diff --git a/main.c b/main.c
index f9f4197..7fb483f 100644
--- a/main.c

Now, I only want the first part, so I reduce the context by typing
's', which lead to:

If I edit this hunk and make _no_modification_, "git apply" fails with:

error: patch failed: main.c:12
error: main.c: patch does not apply
Your edited hunk does not apply. Edit again (saying "no" discards!) [y/n]?

This hunk does _apply_, as it could be staged and committed as-is if I
did not edit it.

This was just a way to reproduce the regression. If you change the
code in a way that would still apply, git-apply would still fails to
apply the hunk. Editing the whole original hunk (ie. not split) works
fine.
