 You may want to put this Helped-by before --- because it's supposed
 to end up in the final commit.

To elaborate further: anything below the three-dash is ignored when
the patch is applied. So it doesn't show up in the commit at all. I
don't really know the reason for this - probably a patch (1) thing.

You could put the patch the Helped-by before your Signed-off-by
(sometimes referred to as S-o-b).

 cache.h (actually git-compat-util.h that cache.h includes) messes
 around with system headers by defining this and that macro. The
 general rule is if cache.h or git-compat-util.h is included, it's the
 first #include, and system includes will be always in
 git-compat-util.h (grep '^#include' shows this). Maybe it's best to
 leave this memcpy alone (and if you do, state so in the commit message
 with the reason).

Yap, after I parsed all the sourcecode

I have find out all the files that cache.h git-compat-util.h and
builtin.h are not the first #include

== test-sigchain.c ==
#include sigchain.h
== sigchain.c ==
#include sigchain.h

And I checked sigchain.h, that it includes very little information.
It didn't import any potential errors. But I think it should be placed
after cache.h to match the consistence of the general rule.
