Selective indication of a comment's original language

Is your feature request related to a problem? Please describe.
Machine translation creates some confusion as to the precision of a commenter's statement.

Describe the solution you'd like
A tag indicating when comments are not being shown in their original language (e.g. "Original in French"). No tag is required when a reader is reading a comment in the language it was written in.

Describe alternatives you've considered
The generic 'language may be machine-translated' warning label was very confusing for readers and detracted from the content of the site, so we removed it.
