Bash autocompletion is broken

[ratijas]

Consider this simple and minimal example:

$ aura -S <Tab>
>>=     aura    check   input.  Please  your    

There is a space after -S, and looking at all those whitespaces in the output, I think they were somehow parser as an input for autocompletion.

Regarding a confusing error message, there is another issue: #639.

Expected behavior

Filter out error messages for autocompletion, i.e. 2&>/dev/null.

Also, autocomplete package names: #640.

Actual behavior

Error message (supposedly) was parsed as an input for autocompletion.

It seems that I will have to revisit both the Bash and Zsh completions entirely.

Having fixed #639 , I can't seem to replicate the original issue anymore. But the fact remains that the Bash completions are horridly out of date. I intend to rebuild them based off Pacman's, which is what I originally did years and years ago.

This fix will be included in the next release, which I can do once we settle on the other two open PRs.
