The problem is that -I works although it should completly break
everything. The only difference is that the tar file won't be
No warning, no error and noone reads changelogs unless something
breaks. (well, most people don't).
"tar -cIvvf bla.tar.bz2 bla" should give:
"bla.tar.bz2: No such file" Since -I reads the files to be included
from a file.
"bla: Failed to open file, bla is a directory" Since tar should try
to create a tra file named bla, which is a directoy.
"tar: cowerdly refusing to create empty archive" Since there
