`jit-lock-stealth-time` defaults to nil (i.e. stealth fontification is
disabled by default) for a good reason: it used to be enabled.

The known downsides are:
- we don't have good input preemption
- it eats up your battery with no clear benefit
  [ Because you end up re-fontifying the whole rest of the buffer after
    every buffer modification.  ]

If we want to keep the buffers fully fontified, then it's crucial to make
sure every tiny buffer modification doesn't force re-fontifying most of the
rest of the buffer.
