diff format documentation: clarify --cc and -c

The description was unclear if -c or --cc was the default (--cc is for
some commands), and incorrectly implied that the default applies to
all the diff generating commands.

Most importantly, "log" does not default to "--cc" (it defaults to
"--no-merges") and "log -p" obeys the user's wish to see non-combined
format.  Only "diff" (during merge and three-blob comparison) and
"show" use --cc as the default.

combined diff format
--------------------
"git-diff-tree", "git-diff-files" and "git-diff" can take '-c' or
'--cc' option to produce 'combined diff'. For showing a merge commit
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
produce a 'combined diff' when showing a merge. This is the default
format when showing merges with linkgit:git-diff[1] or
linkgit:git-show[1]. Note also that you can give the `-m' option to any
of these commands to force generation of diffs with individual parents
of a merge.
A 'combined diff' format looks like this:
