Bug#440843: vim-addon-manager: add bash completion for vim-addons

[Antonio Terceiro]

Hi,

That first implementation really sucked: I made it just as a placeholder
for the actual addon installation checking to be done when the -q option
was implemented.

Thanks for implementing this. :)

I've adapted the completion script accordingly, including checking for
the options that affect the query (-w, -t and -y). In my tests, it
actually worked as we expect.

You'll find the latest version of the completion script attached to this
message.

Cheers,
