   I have discovered that the -T option of Gnu tar version 1.10 may
   have a bug in it.  I created a script that piped file names to tar
   which was invoked with the option '-T -'.  In testing the script,
   I found that when tar was invoked with that option, but no file names
   were sent before the pipe closed, tar used the current directory as 
   the place to select files from for archiving.

   The script line including tar was essentially as follows:

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

   I would have thought that, given the '-T -' option but no file names,
   tar would have simply exited without doing anything.  Is this a feature
   or a bug?

This is a side effect of the general rule that tar does the current
directory when there is no list of names.  The names read from -T are
treated exactly like those read from the command line.
