[Bug-tar] Documentation bug

[Davide Brini]

In section "8.1.1 Creating and Reading Compressed Archives", the online
manual says that it's possible to pass arguments to the compression program:

...
Another way would be to use the '-I' option instead (see below), e.g.:
        
$ tar -cf archive.tar.gz -I 'gzip --best' subdir
...

As far as I can tell, that doesn't work, as tar tries to execute 'gzip
--best' as a single argument:

tar (child): gzip --best: Cannot exec: No such file or directory
tar (child): Error is not recoverable: exiting now
