doc comments content isn't highlighted as comment

    import std/strutils

    # bar
    doAssert "'foo" == "'foo"
    ##[
    foo

    doAssert: not "foo".startsWith "ba"

curious what's used for syntax highlighting; github (via github linguist, see nim entry in https://github.com/github/linguist/tree/master/vendor/grammars) and other tools use https://github.com/Varriount/NimLime which doesn't have this problem

in playground it renders as:

[PMunch]

Since the plaground uses CodeMirror it uses CodeMirror's own syntax support. The specific Nim version can be found here: https://github.com/PMunch/nim-playground-frontend/blob/master/codemirror/mode/nim/nim.js, PRs welcome to add multiline doc comments.
