You converted " ..." -> "..." elsewhere, so why not here?

Is splitting message to two lines a good idea?

Is it time to introduce helper function that does the sync with the
printing?

I must say that I'm to a great fan on adding more lines to hibernation
output. Eats too much vertical space on screen, etc. Do you see real
problems there or are you just trying to "improve" this?

I'm pretty sure sync timing can be easily obtained from other messages
around this one...
