Saw this and it got me curious so I did some google searching, here is what I found:
Open the current version in notepad++
Go to Search>Replace and in the 'Search Mode' section select 'extended'
In the 'Find' box type a double-slash //
in the 'Replace' box type \n// (\n adds a line feed in front of the double-slash)
Click 'Replace All'
At this point you'll have all of the lines returned but may need to edit the file back to the state it was originally in. I noticed that lines 174-175 still run out quite a bit and probably need some extra editing, but that should be easy enough once you get the file back to a normal state.
Hopefully this will get you sorted out, and once you have the files back to a good state make a backup of everything so you don't have to go thru all this again!
