Re: [PATCH v2 0/2] user-manual: new "getting started" section

Felipe Contreras [off-list ref] writes:

That could be easily fixed by making explicit in the syntax that these
are not typical refs: i.e. @stage and @work.

The message I get from that suggestion is that the most sensible approach,
if we are going to add something from this discussion to "git diff", is to
do what you did _not_ quote from my message, which is:

    As to --tree-vs-index counterproposal (was it a counterproposal?),
    except for that I think they are too long to type in practice and need
    to be shortened to be useful, I do not have a fundamental objection
    against it.

IOW, this is about options, and should not be done as syntax sugar that
does a half-baked job of pretending to be refs.
