Regardless of how much look-ahead most parsers currently use, do you  
disagree with my interpretation?

If so, can provide a more formal definition of how you believe the  
spec should be read?

Basically I read it as code-spans can be matched using this regexp: (` 
+) ?.*? ?\1

Although in practice we may 1) require at least one character inside  
the code-span (so `` on its own is not a zero-character code span)  
and 2) we may want to limit them to “markdown paragraphs” which are  
roughly defined as ending when there are two consecutive newlines,  
making the pattern: (`+) ?(.|\n(?!\n))+? ?\1
