positional anonymous attributes don't render correctly

[Mike Bayer]

was a little surprised to see this happen:

>>> from sqlalchemy import *
>>> from sqlalchemy.engine import default
>>> print select([bindparam('b'), bindparam('c')](bindparam('a'),)).compile(dialect=default.DefaultDialect(paramstyle='qmark'))
SELECT ?

!

0.5.7 is preferred here, though 0.6 is acceptable if behavioral changes are needed.

we're safe deduping on clause hash since even in 0.5, the elements in the select's inner columns clause are all ClauseElements (i.e. no strings).

Removing milestone: 0.5.7 (automated comment)
