I agree that it would be much better, but quite hacky I guess. Either writing 
some code which recognizes the filetype in tar's sourcetree, which would be 
(IMHO) bloat, or patching gzip, bzip2, compress etc. to provide an extra-option 
which takes only a filename and tells you wether it seems like the right format 
(hm. this would'nt be hacky at all. Other programs besides tar could also find 
this usefull).
