Minor: IMHO, it is worth to be sorted for better maintenance.

Why did you exclude the file above?

Several chunks in test/vinyl/ directory are not diff-based tests but
either instance configs (e.g. test/vinyl/vinyl.lua) or auxiliary modules
(e.g. test/vinyl/large.lua). I guess we need to check at least the
latter ones.
