No, the problem is that there _is_ no last line.  You have an EOF in the
middle of the line (not every editor will even allow producing that).
Since a line comment has to end with a newline, this is not a line
comment, and a non-comment % is beyond LilyPond's understanding.

One would need to non-trivially rewrite comment matching in the lexer to
get either a nicer error message or just silently a line comment even
though the line does not end.
