[go-nuts] gofmt return multiple function closures

[Neehar Vijay]

See attachment.

I tried returning two closures from one function, but gofmt formats it 
oddly.
It looks fine with a tab width of 4 (like go-tour), but it looks hideous 
with
a tab width of 8.

Is this intentional? Does gofmt assume tab width of 4 or 8?
