saveWidget warning from pandoc

[neuwirthe]

Error message from saveWidget:
[WARNING] Deprecated: --self-contained. use --embed-resources --standalone

The latest version of pandoc 2.19 seems do deprecate option --self-contained

It is called in htmlwidgets:::pandoc_self_contained_html in the lines

pandoc_convert(input = input, from = "markdown", output = output, 
options = c("--self-contained", "--template", template))

so perhaps this needs to be adapted.

Saw that, too.

I created a branch taking care of the problem and submitted a pull request. The modified version is in the repo neuwirthe/htmlwidgets

I also noticed this. Would be nice if they could merge your pull request!
