I seem to vaguely recall there perhaps being a problem with things
like

From: "Foo, Bar" <foo <at> zot.com>, zot <at> foo.com

being tokenized into three email addresses

Foo
Bar <foo <at> zot.com>
zot <at> foo.com

But on the other hand, if there's anything that broken out there, you'd
think that adding a backslash before the comma wouldn't help, either.

Sure, go ahead.  If there's any interoperability problems here, we'll
find out.  But I think it's pretty unlikely.
