Also:
- remove redundant text in doc.go.
- fix (yet more) cases of missing parens in Printf, fallout from
go/types accessors refactoring.
- don't mix spaces and tabs within lines printed by ssa.Function.DumpTo:
it makes it too hard to constructed expected outputs for tests.
(Tabs may appear at line start though.)
Sadly godoc -play won't run this program; it complains it
can't import "code.google.com/p/go.exp/ssa". Any idea why?
