Diff / changes formatting suggestion

[snejus]

I've been finding the way updates are currently being reported a bit confusing. Specifically, this has to do multi-line strings and paths formatting.

Multi-line string

Running beet edit title:Svetimi

For example, if I prepend timestamps to each lyrics line without adjusting the rest of the contents, I am seeing this:

This makes it seem that I have replaced all lyrics except the bits with Bėga bėga. I'm confused why aren't each of the lines treated the same?

Paths

Updating a path format in the configuration and running beet mv --pretend

The issue here is, I think, verbosity: there's a lot of text, and no spacing between each change, so some mental effort is required to figure out what is going on. To compare what the before vs after I still need to look across two lines for each change, unfortunately.

I would personally prefer dropping the before -> after notation and format each change in a single block. I have adjusted this in my fork, and I see these outputs for the two examples above:

Note that I also dimmed the unchanged parts for clarity.

What do you think about this?
