After thinking a bit, I realized I missed a point of Eli's objection
to the implementation of this.  It's that the 'diff' program is required
just to generate the presentation, not just to apply it.

But I don't see any other better ways to summarily present changes to
files.  Ediff maybe?  But that's not so good, and it requires splitting the
window and entering a transient mode.  And I'm not sure it doesn't rely
on the diff program itself (but haven't checked).

Anyway, who works with Emacs in a programming context -- which is
what LSP is mainly for -- that also doesn't have the diff program
for patches, vc-diff, etc?
