I have compiled Gnu tar 1.10 with gcc 1.40 on my Interactive Unix
version 2.2 PC.  Everything works well except the '-T' option with
the '-' argument.  I want tar to read the standard input for file
names to archive and send to the standard output.  In other words,
I create a pipe as follows:

find <options> | sed -f <sed-script-file> | tar -cvf - -T - > <filename>

This works fine until no file names come through the standard input.
If sed completes without producing any output, tar doesn't just exit
without generating any output, as I would have expected.  Instead, it
starts taking file and directory names from the current directory an
archives those.

Is this a bug, or a feature?
