If a text file has 2 lines or more containing 3 (or more) ' or ", it is
considered as a Python executable text script, which is bad because amavisd-new
rely on file to  determine the file type of mail attachments, and any mail which
have more than 3 " or 3 ' in it would be reported as having an executable
attachment.

Steps to reproduce :
$ echo "Test." > /tmp/test.txt
$ file /tmp/test.txt
/tmp/test.txt: ASCII text
$ echo "'''" >> /tmp/test.txt
$ file /tmp/test.txt
/tmp/test.txt: ASCII text
$ echo "'''" >> /tmp/test.txt
$ file /tmp/test.txt
/tmp/test.txt: Python script, ASCII text executable

''' and """ (or more : """", '''''''', etc.) are used for multiline comments in
Python, but that is not a sufficient condition to say if a file is a Python 
script.
