Formatting the code removes all comments

[pbsladek]

#Some comment
database:
  mysql:
    #another comment
    core: null

All comments gets removed. Possible to not remove them?

The underlying library that provides formatting does not (and will not) support comments. If another workable library can be found that preserves comments, I would be happy to switch.

If no existing library can be found and someone wants to take this on, my recommended starting point would be to see if the parser that powers this extension would be willing to accept a PR to add a node type for comment nodes. If comments appear in the tree, then it would just be a matter of writing a function that produces formatted output given the tree.

A related issue tracking the same [lack of] functionality is adamvoss/vscode-yaml#9.

This is an useful recommendation. Inline comment should be returned also.
