To be honest you don't have to add the "-- Not ["0,806,58.03,45.08"]" to the end of the line as we can compare the 2 files and see the changes that you have made..
Assuming you are just changing the co-ords and not writing a completely new file...
I'll try to swing by the locations that you can't reach next time I am in game and see if the fm's line up..
Edit: or are you just making a list that can be used to edit the flightmaster.lua?
http://www.wowhead.com/npc=32571 <-- flight master in Dun Niffelem, The Storm Peaks. I think you need rep to unlock him though. (which my main has...)
http://www.wowhead.com/npc=24851 <-- flight master in Zul'Aman, Ghostlands
I'll have to look closer at the fm in Vashj'ir as one of them unlocks after 100 or so quests there...
