Ah, thanks for the pointer. I would have been surprised if I were the first to discover this. Still I think that breaking AucTeX and the decade-long expectation that '\input foo' works as expected should be avoided at all costs.

In the old thread there have been a few suggestions that would work:

David's suggestion seems to be very robust to me: it would not break traditional code that assume file names without spaces, and it would make quoting unnecessary. There are certainly other solutions as well, e.g. setting the quoted job name in Lua, but David's suggestions seems to be the most elegant.
