I checked Nashbar again, and you're right. It is a single item listing, but you do specify brake or derailleur, so perhaps the brake housing is not compressionless. However, Bike Tools Etc. offers "anti-compression" Delta brand brake cable housing, and the item number, DH-2200 is exactly the same as the Delta derailleur housing they offer.
Thanks for the warning. I think this sort of failure is sufficiently rare that I'm inclined to use the celeste SIS housing if necessary, but if someone can direct me to a source of non-compressionless celeste housing I'll use that instead and restrict the SIS to the shifters on my wifes Bianchi, which has modern Chorus indexed shifters.
