[Bug-tar] Extracting ./usr/bin/[ by name

[Marc Singer]

If I have an archive containing the file ./usr/bin/[, call it
source.tar, should I expect this to work?

  # echo ./usr/bin/[ > files
  # tar xf source.tar -T files

What I've found is that tar won't extract the file.  It generates an
error stating that the file ./usr/bin/[ is not found.  Changing the
recipe slightly does seem to fix the error, but I'm not sure that this
should be expected.


  # echo ./usr/bin/\\[ > files
  # tar xf source.tar -T files

According to the man page, the contents of the -T file are filenames,
not patterns.  Are they really patterns though?
