W292: error message gets shown three times

[jugmac00]

While preparing a code snippet for #947 I encountered another bug

test.py

#: does not raise E265

a = print  #: neither raises E265

#raises

=>

❯ pycodestyle test.py 
test.py:5:1: E265 block comment should start with '# '
test.py:5:8: W292 no newline at end of file
test.py:5:8: W292 no newline at end of file

or minimal
