Are SunOS 4.1 magic numbers wrong ?

[Farooq Butt]

I just created two tarfiles on my SS1+ running 4.1.  
BUT, SunOS claims that:

cdecl.tar:	c program text
foo:		ascii text

BUT, BOTH of these are tarfiles, as demonstrated by:


mrbt% tar tvf foo
rw-rw-r--  0/10 417638 Jul 30 23:52 1990 ./cd.tar.uu
rw-r--r--831/10 303104 Jul 30 23:51 1990 ./cdecl.tar
mrbt% 


      and


mrbt% tar tvf cdecl.tar

mrbt% 



Why is this happening ?  Does the "file" command despise me ?
