My idea of using t for blacklist and nil for whitelist was due to the
fact that for the base cases (always insert label, never insert
labels) I used t and nil, and adding exceptions was as simple as
adding elements to the list, keeping the same first element (t or
nil), though I agree t is logically more adapt for a whitelist and nil
for a blacklist.

However, I'll try to implement this interface later today.

Well, in beamer you can add a sectioning command inside a frame
environment.  This is not the standard behavior but it's legal to
insert a sectioning command inside an environment different from
document.  In addition `LaTeX-current-environment' isn't bullet-proof,
so avoid using it would be nice ;-)
