Title:
  Bash completion whitelisting returns no results when it could return
  some that do not match

Status in “bash-completion” package in Ubuntu:
  Fix Released
Status in “bash-completion” package in Debian:
  Confirmed

Bug description:
  Binary package hint: bash-completion

  When attempting to write a command line to decompress a .tar.xz file,
  tab completion fails:

  mbt at fennel:~$ ls -l *.tar.xz
  -rw-r--r-- 1 mbt mbt 4467540 2010-03-07 15:11 coreutils-8.4.tar.xz
  mbt at fennel:~$ tar xf core

  Pressing TAB multiple times does nothing.

  I think that completion should not be a whitelist thing; that is,
  there should be some way to override the shell's notion of what you
  want it to complete.  For example, if I were to do:

  mbt at fennel:~$ ls -l *.tar.xz
  -rw-r--r-- 1 mbt mbt 4467540 2010-03-07 15:11 coreutils-8.4.tar.xz
  mbt at fennel:~$ tar xf ./core

  … and press TAB multiple times, I still get nothing even though it
  should be perfectly clear to the shell that I really _do_ want it to
  autocomplete on the only possible file in the directory that matches
  the prefix.  This is also a problem when attempting to autocomplete
  names for .zip files that have been renamed to something else entirely
  (such as is the case for MozBackup’s renamed ZIP files, which is
  .pcv).
