Cancelled item

[fancsali]

I propose to add a feature, where one can cancel a list item: - [ ] Foo -> - [-] Foo.

Potentially with a configurable syntax, instead of the simple dash.

Alternatively we could check how GitHub, GitLab and BitBucket do these...

I've not really head about this before. Is there a syntax reference or similar here? Is this part of CommonMarks, for instance?

Well, I am not sure about standardisation...
... but VimWiki seems to do this, and as per StackOverflow (https://stackoverflow.com/questions/54143506/how-to-mark-a-failed-item-on-a-todo-list-in-markdown) it seems to coming from GFM.

Hmm, ok. I guess I can consider it. Can you specify in some more detail what adding this feature entails? I.e., which mappings/commands needs to change behaviour and how.
