Comment(by jason):

 Of course, a big change like this should at least have a vote and
 discussion on sage-devel.

 Rob Beezer points out the preparser doesn't deal so well with newlines, so
 this patch breaks this valid python syntax:

 {{{
 sage: ["1","2","\n;"
 ....: "2","4"]
 ....:
 ....:
 ....:
 ....:
 }}}

 and it never quits.
