Sure.  It's somewhat late here so I'll write those tomorrow.  What
should quote and function do?  That is, should it be (foo . 'bar) or
(foo quote bar)?

The important thing is, though, I actually took a look at the patch
since it's been a while, and I was wrong, what I explained was bug
72434, which I've also attached here.

This patch _actually_ makes it so that (\, foo) [and (\,@ foo)] is
printed as ",foo" in every context, whereas it current prints like that
only if we are inside a quasiquoted form [that is, (\` (\, (\, foo))
prints as "`,(\, foo)"].

[If you're trying the other patch, I should note here as well that that
one builds on top of this one, so the results are incorrect if you only
apply that.  Specifically, when we're not in a backquote, (foo . ,bar)
prints as (foo . (\, bar)) instead.]
