There is a small typo in the comments on line 49 in the source file: go/src/fmt/format.go

I have bolded the particular word below.

The comment currently reads:

// intbuf is large enought to store %b of an int64 with a sign and

It instead should be:

// intbuf is large enough to store %b of an int64 with a sign and

The comment continues in line 50; however, there is no issue with that particular line.

It is a small issue, but it just caught my attention as I was reading through the docs/code.
