Style change: return(x) --> return x

This was discussed and more or less agreed upon on the mailing list. A
huge checkin, but if we just do it and let people adjust the pain will

hand-massaging in order to preserve parenthesis where appropriate:

The semantic match that finds this problem is as follows, although some
hand-massaging was done in order to keep parenthesis where appropriate:
