show large constant strings if the user wants to

I think even though the big Help const is not shown by default, the user
should still be able to see it. And that will be very useful in this particular
case.

The issue I linked is about the eg documentation. This issue is only about adding ability to showing the large const strings to gddo. Whether the package has broken docs or not is irrelevant here. (Even it has broken docs style, not being able to show the string content is still a bug in gddo. It's a tool to show docs, not a tool to judge whether the docs stylle is good or bad.)

If there is interest in viewing long strings separate from the broken documentation issue, then we should add a link to the string in the source code.

I think that's the way to go.

It can already be done for other identifiers. For example, http://godoc.org/golang.org/x/tools/refactor/eg#WriteAST has a link to the source, https://github.com/golang/tools/blob/master/refactor/eg/eg.go#L282. So it's just a matter of adding support to link const identifiers to the source.

Separately, FWIW, gotools works:
