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).
