Subject: [PATCH] Add test cases for quote pairing and footnote label
 normalization

Two edge cases found while checking cdjot against djot.js. Both pass on
main; they pin behaviour that is currently only covered on one side.

smart.test has `''hi''` for doubled quotes as nested, but nothing for a
doubled quote with an empty span. Adjacent delimiters enclose nothing,
so they don't pair and each falls back to its unmatched form -- a right
quote for `'`, a left one for `"`.

footnotes.test covers label normalization on the reference side (a
label spanning lines). The definition side normalizes too, so a wider
gap there still matches the reference; that half was untested.
