Re: [PATCH 10/14] format-patch: add --range-diff option to embed diff in cover letter

I did consider other approaches, such as a more generic option. For
example, --embed=range-diff:<prev>. I also considered supporting more
complex use-cases. For instance, git-range-diff itself accepts the two
ranges in several formats ("a..b c..d" or "x...z" or "i j k"), plus
the creation-factor can be tweaked, so I weighed ways of incorporating
all that detail into the single argument to --range-diff.

However, those are all difficult to use (onerous to type and remember)
and difficult to document. Thus, I opted for simplicity of individual,
straight-forward options (--interdiff, --range-diff,
--creation-factor), which are easy to type, remember, and document.

Yes, that matches my conclusion that it is OK to have these on
separate options that can grow as many meta-diff formats we would
support.
