Do you know if this due to the missing end-of-line at the end? Or is it 
connected to the comment?

I have always found that behaviour of text editors very annoying, 
because at least some programming languages
have trouble reading files which end so abruptly (after all: it is 
called an end-of-line character, not a line-separator
character and with this behaviour there is no way of telling the 
difference between a truncated file and an ordinary
file).
