That's another question.  My question is instead whether it's safe for
`latexenc-find-file-coding-system` to use the `TeX-master` setting in
foo.tex`.  I can imagine cases where that setting could be dangerous
because it tricks the users into accessing a file they shouldn't access.

No, but at least it gives the users a standard way to control whether to
consider it safe or not.
