It's unexpected behavior. You can, after reverting, turn _off_
`hi-lock-mode' and enter your pattern then, but that's clumsy.
Either `hi-lock-mode' should add a function to `before-revert-hook'
which resets `hi-lock-interactive-patterns' or add a function to
`after-revert-hook' which either resets `hi-lock-interactive-patterns'
or adds the interactive patterns to `font-lock-keywords' so that all
patterns are preserved. I'm not sure which behavior is preferable.
For non-font-locked buffers all hi-lock overlays should probably be
removed (and possibly regenerated) too.
