Uses the visited file name, the -*- line, and the local variables spec.
This function is called automatically from `find-file'. In that case,
if `inhibit-local-variables' is non-`nil' we require confirmation before
processing a local variables spec. If you run `normal-mode' explicitly,
confirmation is never required.
Note that this version of this function has been hacked to interact
correctly with tar files - when visiting a file which matches
'tar-regexp', the -*- line and local-variables are not examined,
as they would apply to a file within the archive rather than the archive
