This one is tough because python lets encoding at least be on either the
first or second line of comments. For a file like:

     # foo
     # coding=uft8

py_compile says the error is on line number '0' (I guess because it has
not reached any executable code yet?) so displaying a 'syntax error'
message on line 1 would be rather confusing to the user. I think a
run-time error with a problem like encoding is more descriptive.
