[PATCH] revision.h: add includes of "diff.h" and "commit.h"

Because they are needed by some features included in
"revision.h".

This makes the following just work:

        $ cat >1.c <<\EOF
        #include "cache.h"
        #include "revision.h"
        EOF
        $ cc -Wall -DSHA1_HEADER='<openssl/sha.h>' -c 1.c

Quoting Christian Couder [off-list ref]:

Because they are needed by some features included in
"revision.h".

This makes the following just work:

        $ cat >1.c <<\EOF
        #include "cache.h"
        #include "revision.h"
        EOF
        $ cc -Wall -DSHA1_HEADER='<openssl/sha.h>' -c 1.c

I'm sorry if this is obvious to experienced people, but I don't understand what benefit there is to make such an empty program compilable.
