Comment 3 for bug 386690

Right, presenting that information within the expanded area (beside the unlinkified filename) can be done ASAP. I just don't think it should be the final solution.

I say that mainly because we will be denying copies of sources with expired binaries per bug #316431, and it would be ideal to have an indication that a source has expired binaries (thus cannot be copied) already in the source row, and not require the user to expand each copy candidate row and check.

IMO, if the source can't be copied it shouldn't even be presented, but it falls exactly in the same scenario, calculating it on-the-fly will be too slow for web UI purposes.
