Bugzilla Bug 92655

You need to install a completion function before `--list all` will show
anything.

manuel-64 ~ # bash-completion-config -l
bash-completion-config-0.8

                       | Local  Global |
----------------------------------------
----------------------------------------

manuel-64 ~ # bash-completion-config -l all
bash-completion-config-0.8

                       | Local  Global |
----------------------------------------
----------------------------------------

manuel-64 ~ # ls -1 /usr/share/bash-completion/
bash-completion-config
eix
subversion

manuel-64 ~ # bash-completion-config -g -i eix
bash-completion-config-0.8

 * Installing eix ...                                                     [ ok
]

manuel-64 ~ # bash-completion-config -l
bash-completion-config-0.8

                       | Local  Global |
----------------------------------------
eix                    |          *    |
----------------------------------------

manuel-64 ~ # bash-completion-config -l all
bash-completion-config-0.8

                       | Local  Global |
----------------------------------------
bash-completion-config |               |
eix                    |          *    |
subversion             |               |

Expected Results:  
`bash-completion-config --list all` should list all global completion functions
that are available for install.

Fixed in 0.8-r2.  Also fixed --list to ignore files matching *~ so backup files
don't show up.
