blog: correct stale links to specific line numbers to old versions of the code

If ?#L312 is updated to correspond with the current strings.go file, omitting the needless "?", I think that would be #L493.

Pending code review the developers might want to change #L24 to #L22.

It took me a second to figure out what this bug is about.

The blog post contains links to stuff like "[[http://golang.org/src/pkg/strings/strings.go?#L312]" which used to be correct in old versions of Go but no longer works.

Regarding the proposed change from #L24 to #L22, I presume the link would be to the beginning of the godoc comment.
