String diff for UUIDs can use strings.Join syntax which makes it more confusingΒ #356

Description

This is a similar topic as #274 and #195, but when using cmp to diff UUIDs.

When the UUIDs are very different, the output looks like:

  	ID: strings.Join({
- 		"e93d2d8b-7d2a-4c62-967a-b189347a4fa2",
+ 		"7e93c401-4e27-3b83-7edc-2dd0803c39b3",
  	}, ""),

The strings.Join adds unnecessary noise here, ideally it would be displayed as:

-  	ID: "e93d2d8b-7d2a-4c62-967a-b189347a4fa2",
+ 	ID: "7e93c401-4e27-3b83-7edc-2dd0803c39b3",

However, if the UUIDs have common characters, the output gets really verbose, and isn't particularly useful:

  	ID: strings.Join({
- 		"217d",
  		"6",
- 		"7ef-d686-4107-ab35-347ed6c91a22",
+ 		"68416ab-a20e-48ae-afaa-8df7b91a4af3",
  	}, ""),

Is there a way to avoid this specialized string handling and have it never use the strings.Join output but show a simpler remove/add for string fields?
