Hi Philipp, very sorry for such a long delay to reply.

I don't use indirect buffer, so please bear with me if I'm missing
points. So far AUCTeX didn't pay attention to indirect buffers, so I'm
afraid that numerous potential inconsistencies remain there even if your
suggestion is incorporated. For that reason, I'm reluctant to go in a
direction to tame AUCTeX to work properly with indirect buffers. Why do
you edit in an indirect buffer? (Even if there is good reason to do so,
I feel that it's enough to make C-c C-c (and similar commands) ask
whether to switch to base buffer when you are in indirect buffer.)

Regards,
