file(1) contains a rather complete set of such heuristics and
has been stable for a long time. AFAIK libmagic is free and
GPL-compatible.
Yes, i believe so. My concern w/ using libmagic would be
portability, and handling the case where libmagic is not
available. I envision the feature to be non-optional.
Also, it might be nice if you could call this facility from
coding systems (after all, what else is a BOM but file magic?)
This kind of thing really doesn't need to be in Lisp, and might
benefit from being in C.
Certainly, in C it can be much faster.
