cat: don't prefetch files unless the output requires it...

cat: don't prefetch files unless the output requires it It's a waste to cache lfs blobs when cat'ing the raw data at best, but a hassle debugging when the blob is missing. I'm not sure if there are other commands that have '{data}' for output, and if there's a general way to prefetch on that keyword. It's interesting that the verbose output seems to leak into the JSON output, but that seems like an existing bug.
