It is impossible to implement in listed-incremental mode, because it
contradicts the basic principles of this mode. Listed-incremental
operates on *directories*, not files. Implementing --no-recursion the
way you propose would render it useless.

Although currently it is possible to specify regular files on the
command line in listed-incremental mode, this is not recommended and
will probably be removed in future releases. In other words, doing
something like:

  find . -type f | tar --listed-incremental -c -f archive -T -

is wrong.  

The only feasible semantics of "--listed-incremental --no-recursive" I can
think of is ``do not descend into subdirectories more than on level 1'',
which was implemented in this patch.
