Re: should `minibuffer-complete' use `abbreviate-file-name'?

    I don't see how that contradicts what I said either. In the user's use case
    that I cited, FROM is ^/exe and TO is /very-long-path-here/exe. Both FROM
    and TO are equivalent names in terms of their effect, and both effectively
    refer to the same directory, /very-long-path-here/exe.

I guess I do not understand your proposed usage.
I thought I did, but I can't follow this.
