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.

  $ hg init a
  $ cd a
  $ hg init b
  $ echo x > b/x

Should print nothing:

  $ hg add b
  $ hg st

  $ echo y > b/y
  $ hg st

Should fail:

  $ hg st b/x
  abort: path 'b/x' is inside nested repo 'b'
  [255]
  $ hg add b/x
  abort: path 'b/x' is inside nested repo 'b'
  [255]

Should fail:

  $ hg add b b/x
  abort: path 'b/x' is inside nested repo 'b'
  [255]
  $ hg st

Should arguably print nothing:

  $ hg st b

  $ echo a > a
  $ hg ci -Ama a

Should fail:

  $ hg mv a b
  abort: path 'b/a' is inside nested repo 'b'
  [255]
  $ hg st

  $ cd ..
