So this has been sitting for a while...

The patch looks okay to me.  It's a bit unfortunate that it adds yet
another way to store partial strings; I have a patch which fixes things
in a more unified way, but my patch rewrites too much to go on the
release branch.

So I think it would be nice if this patch could go to emacs-26.  I
presume you don't have copyright assignment (so the patch should be
marked as a tiny change)?

And this newline in the middle of the docstring should be fixed.
