go/printer, gofmt: fine tuning of line spacing
- no empty lines inside empty structs and interfaces
- top-level declarations are separated by a blank line if
a) they are of different kind (e.g. const vs type); or
b) there are documentation comments associated with a
declaration (this is new)
- applied gofmt -w misc src
The actual changes are in go/printer/nodes.go:397-400 (empty structs/interfaces),
and go/printer/printer.go:307-309 (extra line break). The remaining
changes are cleanups w/o changing the existing functionality.
Fixes issue 2570.
