Thanks for the quick answer. A patch follows.

That's unusual. At least we don't need both files and packages mixed for
completion which is a good thing.

This patch allows stuff like ./dir/zsh.deb or ./../../somewhere/zsh.deb.
Are those valid? If it is strictly current directory only, this might
need _path_files instead of _files.

Is the same feature applicable to apt-get or aptitude? 

I've also corrected the tag/description mixup for the release names and
package versions and made / or = auto-remove the space suffix after
package names.
