To reproduce:

  emacs -Q
  [visit some versioned file under Git control]
  M-x set-variable RET diff-font-lock-prettify RET t RET
  M-x fringe-mode RET right-only RET
  C-u C-x v = SOME-REVISION RET RET

The last command reports changes of the file since SOME-REVISION.  But
because the left fringe is unavailable, there's no insert/delete
indicators at all, not even the original ones displayed when
diff-font-lock-prettify is nil.

I think in this case we should keep the original indicators.
