Are there any problematic aspects of the patch that need to be
discussed or considered before installing the patch?

IOW, why are you soliciting our opinions, instead of just going ahead
and installing?

It looks to me like it adds a new feature, not just solves a
performance problem?

Some minor comments to the patch itself:

> +(defvar-local completion-lazy-hilit nil
> +  "If non-nil, request completion lazy highlighting.
> +
> +Completion-presenting frontends may opt to bind this variable to
> +non-nil value in the context of completion-producing calls (such

> +strings with highlights of the matching parts.

If this is intended to be bound by frontends, why is it defvar-local?
I thought let-binding buffer-local variables is a tricky business that
could have unexpected results?

Also, I think this doc string should reference
completion-lazy-hilit-fn.

> +(defvar completion-lazy-hilit-fn nil
> +  "Used by completions styles honoring `completion-lazy-hilit'.

This should mention "function", since just "Used to..." doesn't convey
that, and "-fn" could also mean "file name", not just "function".

> +(defun completion-lazy-hilit (str)
> +  "Return a copy of completion STR that is `face'-propertized.
                                              ^^^^^^^^^^^^^^^^^^
Strange quoting.  "face" is not a symbol that we want to have a link
to, is it?

I see a few more places in the doc strings that will "need work", but
that can be done later.

What did you want to say in NEWS about this?  If it's just a
performance improvement, we don't normally mention them in NEWS.

Thanks.
