Fun.  The -U<n> option in "git diff-index -U9" implicitly turns
"--patch" on, but it is hard to say that the same option in "git
format-patch -U9" turns "--patch" on, as it is in effect even
without the -U<n> option.

It makes readers wonder what, if anything, needs to be done for "git
diff -U9", but let's leave it out of the scope of this change, which
is strict improvement for "format-patch" documentation.

Thanks.
