[Bug-tar] problems with --no-recursion in tar 1.15.1

[Philip Lawrence]

given a directory, tmpdir, containing subdirectories

1) "tar --no-recursion -vcf tmp.tar tmpdir" will create a tar file with 
only one entry (tmpdir), and subsequent operations will be consistent 
with no-recursion.

2) "tar --no-recursion -vcg .snapshot f tmp.tar tmpdir" will not create 
the same result. All files and subdirectories within the directory, 
tmpdir, will be added to tmp.tar. This seems to contradict the operation 
intended.

Is this a known bug that has been, or will shortly be, corrected?
Is this a bug at all, or merely a misunderstanding, on my part, of the 
intended operation?
