`InteroUses` should populate `loclist`

[stellarhoof]

Right now, InteroUses behaves no differently than searching naively. If I wanted this, I'd search for the identifier myself. This adds a couple of problems:

• Noise in the buffer (hlsearch is set by default)
• False positives (even strings in comments are selected)

+1 on of this, but wouldn't it be better to populate quickfix, instead of loclist, as there might be usages in other files?

[stellarhoof]

Better yet, provide an option for it. If it hardcodes one it might conflict with other plugins (e.x. linters). And so far from my testing, it only return usages for the current file. Maybe I'm missing something?

Ah also provide an option for customizing auto-open behavior :)

Yeah, my implementation for Uses is definitely a hack 😃 I'd be happy for a better implementation, but I'm not sure the best route forward there.
