Note that what you want, i.e., to distinguish behaviour depending on the
location of the call stack is cheesy, at best. Think about macros,
user-defined functions, etc.

The Emacs' answer to this is usually to check if call to a function is
interactive, or not.

So, if you want to implement it properly, you may want to look into that
direction.

Of course, meawhile, do not rely on undefined behaviour :)
