Bug Report

Currently youtube-dl allows you to --abort-on-error I'd like to request an option called --abort-on-warning as I'd like to not download a file if it doesn't contain subtitles or other such warnings that can occur when you're downloading from a site.

Alternatively maybe a switch such as --warnings-as-errors so warnings are treated as errors so --abort-on-error can be used instead.

+1 on this request. A failure to get a subtitle file can go unnoticed otherwise.
