No one is going to use the callsign "MH370" on freq (which isn't the flight's actual callsign, anyway). But at least we have times/rough intent of the transmission. Looks completely normal to me, even the second confirmation of climbing to FL350.
Obviously these were not the actual words used in the transmissions. Normally, all these radio calls would be in English with perhaps a word or two in a local language.
Phrases like 'runway ready, permitted to take off' will never be heard in real world ATC clearances.
If this leaked transcript was the original source of 'all right, good night', I sure wouldn't read too much into it.
