Auto link trailing punctuations(' and ")

[Yusuke Inuzuka]

Spec says

Trailing punctuation (specifically, ?, !, ., ,, :, *, _, and ~) will not be considered part of the autolink, though they may be included in the interior of the link:

But the implementation

cmark-gfm/extensions/autolink.c

Line 58 in 6a6e335

 if (strchr("?!.,:*_~'\"", data[link_end - 1]) != NULL) 

handles ' and " as excluded punctuations.

Which one is correct?
