But you even don't know that. My original problem came from the fact
that, if a user applies partial completion, the file name is already
substituted, and in the other case it isn't.
Meanwhile, I tend to regard it as a bug in `PC-do-completion', like
the others.

For file name operations, this would be even an implementation
restriction whether they can apply substitute-in-file-name, or not.
More general, it might be said under which circumstances it is
harmless to apply substitute-in-file-name (for local cases, where the
result of substitution isn't returned by the function), and when not.
