I didn't take the time to analyze your implementation in detail, but I
think it fails at REFILL, which would advance by a single line in
EXECUTE-PARSING-FILE but which will skip to the end of the file with
your implementation.

An easy way to test that is to do POSTPONE \  with your implementation
which would skip more than just a single line.

(I was looking at this example that removes comments starting on '#'
from a file:
