that's kind of a red herring, isn't it?  after all, file(1) is
*defined* to look inside the (regular and non-empty) file to intuit
the type.  lpr (et al), on the other hand, is defined to print things.

if anything, something that wants to intuit a file's type should ask
file.  or the mythic libmagic.
