[PATCH v4] Documentation fix: git log -p does not imply -c.

[Adam Monsen <haircut@gmail.com>]

Relates to the thread with subject "frustrated forensics: hard to find
diff that undid a fix" on the git mailing list.

    http://thread.gmane.org/gmane.comp.version-control.git/168481

I don't wish for anyone to repeat my bungled forensics episode.
Hopefully this will help others git along happily.

 combined diff format

-with "git log -p", this is the default format; you can force showing
-full diff with the '-m' option.
+Any diff-generating command can take the `-c` or `--cc` option to
