Support Go 1.19 godoc formatting

[ainar-g]

See golang/go#51028 golang/go#51082. It seems like this should mostly be a matter of updating some dependencies, but I don't know for sure.

@ainar-g
Sorry, I just noticed this issue.
It looks the linked issue is unrelated. Is it golang/go#16666 or golang/go#51082?

[ainar-g]

@go101, the latter, yes. Apologies, hand copying strikes again, heh.

[zigo101]

If it is applicable, Golds will use the official code as dependency.
If this is not possible or there are difficulties in this way, then Golds might render the comments with slightly different rules.

I'm not sure I follow, sorry. I've built a local copy of golds using the latest golang.org/x/tools as well as a development version of Go 1.19 from master, but the resulting binary doesn't show headers or lists from the proposal in the web interface.

gotip version -m $( which golds )

This feature has not been implemented in Golds yet.
Go 1.19 will introduce a go/doc/comment package, Golds will use it if applicable.
But it is not guaranteed to be implemented as such.
That means Golds will only write some links but not support headers and lists.

[ainar-g]

Ah, I see, thanks.

@ainar-g

A new -render-doclinks option is added to render links in doc comments.
Some implementation details might differ from the official ones.

And I decide not to render bullets and headings.

A new release will be made several days later.
