Multiple footnotes

[allenwu1973]

Hi

I found adding multiple footnote reference together, without space, does not work in cmark-gfm.
This does work in pandoc and kramdown.

Thank you

This is my test [^ref1][^ref2].

[^ref1]: some ref
[^ref2]: other ref

Here is a naive patch that seems to fix this, not sure if this the right thing to do.

I independently came to this same conclusion and roughly the same patch! This just got merged in, cheers.
