My original motivation of the series was to just make the new dwim
work :)  Because that's adding some magic, the secondary motivation
became improving the UI, to help users see which dwim was used.  I
felt like this was going to be one of those improvements, especially
after we get rid of the "Preparing ..." line.

I do however like your suggestion of the "Preparing worktree (_branch
disposition_)", as that doesn't add more lines to the output, while
still giving a good indication of what exactly is happening.  At that
point just showing "HEAD is now at ..." is fine by me, and doesn't
require adding the hidden flag to 'git reset'.  So I'm happy just
dropping the change in the message here, which will simplify things.

Thanks for the suggestion!
