This is probably a godoc problem, actually. The code looks like this:

type Pool struct {
    local     unsafe.Pointer // local fixed-size per-P pool, actual type is [P]poolLocal
    localSize uintptr        // size of the local array

    // New optionally specifies a function to generate
    // a value when Get would otherwise return nil.
    // It may not be changed concurrently with calls to Get.
    New func() interface{}
}

Godoc strips out the non-exported fields but doesn't trim the whitespace separating them.

That is what we found in the previous issue, as mentioned in golang/gddo#243.

This is a known problem and non-trivial to fix in general (sometimes we want the whitespace) with the current library support. There may be simple heuristics that might fix the problem in most cases.

This is a non-urgent issue.

Duplicate of #18264. This is a go/printer issue actually. Closing this since there has been more activity on that issue.
