I disagree.  It's clearer to state, when it's the case,
that a given operation acts on a file or a dir, or on
files and dirs.

We do that pretty consistently in Dired and some other
areas of Emacs.  We should do it wherever it makes
sense, and it makes sense wherever someone might not
understand that the operation applies to either/both.
