Basically, this would go along with /cline, or /echo [color] etc. Simply returns the color of the Nth line. Preferably not limited to @windows.

Now that I think about it, it might be kind of nice to allow /cline to work for other window types as well, although I have no use for this right now.

Agreed, although I'd prefer it to be $line().color instead. Maybe it could be added into $fline and $sline as well..
