New issue 4087: Column.copy() doesn't copy comment attribute
https://bitbucket.org/zzzeek/sqlalchemy/issues/4087/columncopy-doesnt-copy-comment-attribute

Rudolf Cardinal:

In SQLAlchemy 1.2.0b2, the `Column.copy()` function doesn't copy the new `comment` attribute; it would need an additional `comment=self.comment` line in its call to `self._constructor()`. Reproduction:

    from sqlalchemy import Column, Integer
    a = Column("a", Integer, comment="hello")
    b = a.copy()
    a.comment  # 'hello'
    b.comment  # None
