Yes, this is awkward. Here comes the next candidate for quoting. In pull-fetch-param.txt:

The remote ref that matches <src>

Again, if the optional plus `+` is used, the local ref

"man git-fetch" and "man git-pull" show:

              The  canonical  format of a <refspec> parameter is ?<src>:<dst>;

I.e. the first and second + were swallowed, but not the third one.
This is the fix for asciidoc 8.0.0:
	`$$+$$?<src>:<dst>`; that is, an optional plus `+`, followed

Here is another fix that works with asciidoc 8.0.0:
	`\+?<src>:<dst>`; that is, an optional plus `+`, followed

Results in

Does the backslash notation work with asciidoc 7?
