You're right about that.

That's better, but it risks confusion over the notion of
"selection", especially in the context of marking or using
marks (a "selection" of files).

This might be better: "No files specified"
Or this: "No files chosen"

Meme combat - same thing.

The return value of `dired-get-marked-files' needs to be tested as
soon as it's available.  When it is nil we must not call
`dired-read-shell-command' or do anything else - just raise a
`user-error'.

This is a general change that needs to be looked for and made
wherever appropriate.
