@Kovid (or others in the know) - after applying the tweak (and restarting calibre), checking "Update title sort" in the Batch Edit dialogue doesn't apply the tweak. Am I doing something wrong here? On the individual Edit Metadata dialogue, the "Automatically create the title sort entry..." arrow works perfectly.

@ chaley - Yeah, the same is true of Spanish (although now we're kind of talking about prepositions more than articles). I figured that multi-lingual title sorting would have enough challenges as it was. My bootleg workaround for names has been to omit the space: DeGaulle, LaFontaine, etc. It ain't always pretty and I still struggle on making that choice (should John le Carre sort as "Carre, John le" or "LeCarre John"... "Guin, Ursula le" or "LeGuin, Ursula"?), but it doesn't happen enough (in contrast to leading articles in titles) for me to be driven completely nuts.

@opitzs - thanks. I will add them to the thread list too.
