umpf: omit hash/version info on show without --identical

[a3f]

The topic-range and hashinfo information won't be used later on, unless --identical is given. It thus makes sense to ignore them in umpf show too, unless the user requests them with --identical.

So there are basically two use-cases for umpf show:

1. For the user to look at and see what is going on
2. To pipe it into a file as a starting point for a new umpf

You're only thinking about the second one. It would be really confusing to change the default for the first one.

I think the second use-case actually deserves a separate command. Maybe umpf init-from-umpf? That new command should skip the extra output from show_diff() and with --identical only add umpf-hashinfo.

A user can find out what's happening with git show too. Myself, I use umpf show only to pipe it into a file.

I don't like the init-from-umpf name, because to me it's just a shorter show. Should I add a --nonidentical which does only matter for umpf show?

An option works for me. And while I don't like --nonidentical all that much, I don't have a better idea either, so go for it. Or maybe --non-identical? I don't mind either way.
