I tried to actually compare the two versions, and found out that the
lexical-binding does nothing at all during the script execution,
regardless of whether there is an empty line or not.  Is this a bug or
an expected behavior?

FTR, when opening the file in a buffer, the property line in a file
without empty line is properly recognized, whereas in the file with
empty line it is not recognized.
