Oh, you mean keep adding when the min_width eq-ness doesn't change? I
guess that could work, but I don't see how that'd simplify anything.

I've tested, and it does. It's only apparently in specs like
" (%l,%c)", though.

Yes, when called from the mode line we're postponing the stretch
computation until the :propertize run is actually over (in the
multiple-% case).

Well, the stretch isn't realised until there's something to stretch too.
So at the end of the buffer it's a NOOP, which seems natural to me.
But we could change that, of course.
