While trying to implement footnotes, what would be the best indentation rules for continuation? Should it be done a bit similar to the way CommonMark is already working for list?
PHP Markdown Extra and Pandoc for example require a fixed indentation of a tab, but in the philosophy of CommonMark shouldn’t we indent on the first non-whitespace char following the [^xxx]:
This is a text[^1]
[^1]: This is footnote
> This is quote block
Tis is not a continuation
The problem is that the footnote reference markers can be quite long. (I often use fairly descriptive ones, not just numbers.) So I think doing it the way pandoc does makes the most sense.
Implementations could consider the label, maybe including the square brackets, to be a fixed length, say 3 characters, no matter its actual length, and then apply the usual indentation rules.
